How to fix Google Classroom stuck at loading screen?

Google Classroom stays on the loading screen when the browser cannot finish loading your classes: a second Google account, an extension, damaged site data or the network stops it. Sometimes Google's own servers have an incident. Check the status page first, then open Classroom with only your school account signed in.

Facts checked on 14 October 2026. Steps written for classroom.google.com in Chrome 155 on Windows 11 (25H2 and 26H2) and Windows 10 22H2; the Classroom app on Android and iPhone.

What it means when Google Classroom is not loading

Classroom is a web app. When you open classroom.google.com, the page first checks which Google account you are using, then fetches your classes, posts and files from Google's servers. The loading bar you see is the wait between those two steps. If any part of that chain fails quietly, the bar keeps running and no error appears.

That is why the problem has so many names. People search for Google Classroom not loading, won't load, infinite loading or crashing, and the reason behind each one can be different. The page does not tell you which one you have, so this guide gives you three short tests that do.

Why Google Classroom won't load, from most to least common

Most often the browser holds more than one Google account, or an extension or old site data gets in the way. Less often Google itself has an incident, or the network blocks part of Classroom. Rarely the account is not set up for Classroom at all. The volunteer Product Experts in Google's Classroom forum give the same first steps again and again: sign out of every account, clear cookies and cache, try Incognito, turn off extensions.

When Google Classroom itself is down: the 2026 incidents

Google posts problems with its school and business services on the Google Workspace Status Dashboard. Classroom has its own row there, next to Google Sign In, Google Drive and Chrome Browser. The history on that page shows that Classroom outages are real but short and rare. We read it on 14 October 2026.

• 29 April 2026, 18:30 to 20:45 UTC. Google wrote that affected users may experience issues accessing Classroom and that no workaround was available. The cause was an internal software migration, which Google rolled back.
• 13 to 18 August 2026. Admins and some teachers got permission errors on Classroom's new web homepage. Google's workaround was to open other views from the left-hand menu. The mobile app was not affected. The fix was complete at 22:30 UTC on 18 August.

How to fix Google Classroom not loading

Start with Fix 1 and Fix 2: together they take about three minutes and solve the problem for many readers. Fixes 3 to 6 repair the browser. Fix 7 is for the network, and Fix 8 is for the Classroom app on a phone.

Fix 1. Check whether Google Classroom is down for everyone

2 minutesNo riskBefore you change anything, and always when classmates report the same problem.

Google posts Classroom incidents on the Google Workspace Status Dashboard. If Classroom is marked there, the fault is on Google's servers and nothing on your device will change it.

1. Open https://www.google.com/appsstatus/dashboard/ in any browser or on your phone.
2. At the top, read the line under the introduction. No incidents means Google has nothing open for any service.
3. Find the Classroom row in the table. The columns are the last eight days, and the last column is today.
4. Compare the icon in today's column with the legend above the table: Available, Service information, Service disruption or Service outage.
5. Check the rows Google Sign In and Google Drive too. Classroom needs both to show your classes and files.
6. If any of them is marked, select it and read Google's text: the symptoms, a workaround if there is one, and the time of the next update.

Times on the dashboard are in UTC. The page also has View incident history, where you can see whether the problem was fixed, and an RSS feed if you want to be told about new incidents.

Fix 2. Sign out of every Google account and open Classroom with your school account only

3 minutesLow riskYou are signed in to more than one Google account in the same browser, for example a personal Gmail and a school account.

Google says that when several accounts are signed in it sometimes cannot tell which one you are using, and in many cases the default is the account you signed in with first. Classroom, Drive files and pictures can then load with the wrong account and stall.

1. Make sure you know the password of every account, because you will sign in again. Google advises having backup verification methods set up before you sign out.
2. Go to https://www.google.com and select your profile picture or initial at the top right.
3. Select Sign out of all accounts.
4. Open https://classroom.google.com and select Go to Classroom if you see it.
5. Sign in with your school email address, the one that looks like *[email protected]*, and its password. Do not add a second account yet.
6. Wait for the class cards to appear. Then check the profile picture at the top right: it should be your school account.

Need your personal account in the same browser later? Add it after the school account, so that the school account stays the default. Better still, give the school account its own Chrome profile with the steps below: then the two accounts never meet.

1. In Chrome, select Profile (your picture at the top right of the window).
2. Select Add Chrome profile.
3. Sign in with your school account when Chrome asks, or continue without an account and sign in to Classroom inside the new window.
4. Choose a name and a colour, for example "School", so you can tell the windows apart.
5. From now on, open Classroom only in this profile. You switch profiles with the same Profile button.

• You see "You can't use Classroom with this account." Google says you signed in with an account Classroom does not accept for you. Sign out and sign in with the school account or a personal Google Account.
• You see "Your administrator hasn't activated Classroom" or "This service has been disabled by your admin." Classroom is not turned on for your school account. Only the school's IT admin can change that, so tell your teacher.

Fix 3. Test Classroom in an Incognito window, then turn off extensions

5 to 10 minutesLow riskClassroom still keeps loading with only your school account signed in.

An Incognito window starts without your cookies and, by default, without extensions. If Classroom loads there, the cause sits in your normal profile, and an extension is the most common one. A forum user reported that Adblock Plus stopped Classroom on a Windows 11 PC.

1. In Chrome press Ctrl + Shift + N, or select More and then New Incognito window. In Edge or Firefox open a private window from the browser's menu.
2. Open https://classroom.google.com in the private window and sign in with your school account.
3. If Classroom loads, close the private window and go back to a normal one.
4. In Chrome, select More (the three dots), then Extensions, then Manage extensions. You can also type chrome://extensions in the address bar.
5. Turn every extension off with its switch.
6. Reload Classroom. If it loads, turn the extensions on again one at a time and reload after each one.
7. When Classroom stops loading again, the last extension you turned on is the cause. Leave it off, select Remove, or allow classroom.google.com in its own settings.

• Classroom does not load in Incognito either: your profile is not the cause. Skip Fix 4 and go to Fix 5, or check the network with Fix 7.
• It loads in Incognito, but turning off all extensions does not help: stored cookies or cached files are left as the suspect. Go to Fix 4.

Fix 4. Clear cookies and cached files in your browser

5 minutesLow riskClassroom works in an Incognito window but not in a normal one, and the extensions are not to blame.

Your browser keeps sign-in cookies and copies of Classroom's files. When they no longer match what Google's servers send, the page can stop halfway. Google's Product Experts list this step in almost every Classroom loading thread.

1. Open Delete browsing data. Press Ctrl + Shift + Delete. Or select More (the three dots at the top right) > Delete browsing data.
2. Choose how far back to delete. Select a time range at the top, such as Last hour. To clear everything, open More next to the ranges and choose All time.
3. Choose what to delete. Check Cached images and files. Check Cookies and other site data too if a site will not sign you in. Uncheck anything you want to keep.

   

4. Delete the data. Select Delete from this device.

These steps were written for Chrome for Windows (screenshot: Windows 11 26H2). The full page with the other versions and what each result means: Clear the browser cache and cookies

Edge and Firefox have the same two boxes under other names. The full steps for both are in Clear the browser cache and cookies. After the deletion, close every browser window, open the browser again and sign in to Classroom with your school account only.

Fix 5. Update the browser and make sure it is one Google supports

5 minutesNo riskClassroom works in another browser or on another device, but not in this one.

Google writes that on an older or unsupported browser some features might not work or an application might not open. It supports the latest Chrome and the current and previous versions of Firefox, Safari and Edge, with cookies and JavaScript turned on.

1. In Chrome, select More, then Help, then About Google Chrome.
2. Chrome checks for updates on this page. With nothing waiting it says Chrome is up to date and shows the version number.
3. If you see Relaunch, select it. Your tabs come back after the restart.
4. Edge and Firefox also check for updates on their own About page, which you find in each browser's menu under Help.
5. Open Classroom again in the updated browser.

If one browser keeps failing after all of this, use another supported browser for Classroom. Google's own advice in its Chrome help is to uninstall Chrome with its browsing data and install it again when the profile itself is damaged.

Fix 6. Turn off graphics acceleration when the page is blank or black

3 minutesLow riskClassroom shows a blank, black or flickering page in one browser on a PC, while other devices are fine.

Google's Chrome help names hardware acceleration as one cause of pages that will not work: there could be a problem with how your computer's hardware works with Chrome. Turning it off makes the browser draw pages without the graphics card.

1. In Chrome, select More, then Settings.
2. Select System at the bottom of the left menu, or type chrome://settings/system in the address bar.
3. Turn off Use graphics acceleration when available.
4. Close Chrome and open it again, as Google's help advises.
5. Open Classroom again.

In Microsoft Edge the switch has the same name. Open Settings, then System and performance, then System, or go to edge://settings/system, and turn off Use graphics acceleration when available.

Fix 7. Check the connection and any network filter

5 to 15 minutesNo riskClassroom does not load in any browser on this device, or only on one Wi-Fi network.

Google's sign-in help says you must have an active internet connection, and Classroom fetches classes, Drive files and videos from several Google addresses. A weak signal or a filter that blocks one of them leaves the page half loaded.

1. Open another site, such as https://www.google.com, to see whether the connection works at all.
2. Turn on your phone's mobile data, turn off its Wi-Fi, and open Classroom on the phone. Or connect the PC to the phone's hotspot for one test.
3. If Classroom loads on the other network, the problem belongs to the first network, not to your device or account.
4. Restart the modem and the router: unplug them, wait at least 30 seconds and plug them back in.
5. On a school network, tell your teacher or the school's IT team the time and what you saw. Only they can change the school's filter.
6. At home, check parental controls, a security suite's web filter or a VPN. Pause the filter for one test only and turn it back on afterwards.

If no site loads on the PC, the problem is the connection itself. The full check for Windows 11 and Windows 10, with the network troubleshooter and the ping test, is here: How to check your internet connection in Windows

Fix 8. Fix the Classroom app on Android or iPhone

5 minutesLow riskThe Google Classroom app keeps loading, shows an empty screen or closes, while the website works in the phone's browser.

The app keeps its own copy of your classes and files on the phone. An old version or damaged app data can stop it, and Google notes that only current systems get the latest app: Android 5.0 Lollipop or later, iOS 11 or later.

1. Update the app first: open Play Store or App Store, search for Google Classroom and select Update if you see it.
2. On Android, open Settings, then Apps, then Classroom, and select Force stop.
3. On the same screen, select Storage & cache, then Clear cache. Google says this deletes temporary data and the app may be slow the next time you open it.
4. Open Classroom again. If it still fails, return to Storage & cache and select Clear storage. This removes the app's data on the phone, so you sign in again and offline files are gone.
5. On iPhone, touch and hold the Classroom icon, select Remove App, then Delete App and Delete. Install Google Classroom again from the App Store.
6. Sign in with your school account. If the app asks to add another account, choose the school one.

Google also says that all features of the app need Google Docs, Sheets and Slides on the phone. If attachments do not open from Classroom, install those apps from the same store. When the app still fails, use classroom.google.com in the phone's browser until it is fixed.

If Google Classroom is still not loading: what to check and what to send

When Classroom fails in every browser, on every network and on more than one device, the problem is almost certainly the account or Google's side. Neither can be fixed on your PC. What helps now is a clear report to the person who can act on it.

• Students: tell your teacher. Google's help says that if you cannot sign in with the correct account, the school may not have activated Classroom for new users, and only the admin can change that.
• Teachers: ask the school's Google Workspace admin. If you signed in as a student by mistake, the admin can change your role to teacher.
• Admins: check the Classroom row on the status dashboard, then open a support case from the Admin console. A Google Product Expert gave this exact advice to an admin whose Classroom homepage would not load.

Inside Classroom on a computer you can also report a problem to Google: select Help in the bottom-left corner, then Send feedback. In the Android app it is Menu, then Help, then Send feedback. On iPhone it is Menu, then Send Google feedback.

How to stop Google Classroom from getting stuck again

One habit saves the most time: when Classroom fails, open it once in an Incognito window with the school account. If it works there, your profile needs Fix 2 to Fix 4. If it does not, look at Google's status page and the network instead.

Frequently asked questions

Why is my Google Classroom not loading?

Most often because the browser holds more than one Google account and Classroom opens with the wrong one, or because an extension or old cookies stop part of the page. Less often Google itself has an incident, which you can see on the Google Workspace Status Dashboard. Check the status page first, then sign out of every Google account and sign in with your school account only. If it still spins, try an Incognito window and turn off your extensions. These three steps cover most cases and take under ten minutes.

Is Google Classroom down right now?

Open the Google Workspace Status Dashboard at google.com/appsstatus/dashboard and find the Classroom row. The last column is today, and the legend shows Available, Service information, Service disruption or Service outage. Google lists real Classroom incidents there, such as the one on 29 April 2026, when users had issues accessing Classroom for about two hours. Sites that count user reports can show a spike too, but they do not know the cause. If the dashboard is clear and only you have the problem, the cause is on your side.

Why does Google Classroom keep loading forever on my Chromebook?

The same causes apply as on a PC: a second account, an extension or the network. Google says you do not need an app on a Chromebook, you use Classroom in the browser. Make sure you signed in to the Chromebook with your school account, open classroom.google.com and check the profile picture. School Chromebooks are managed by the school, so extensions and network filters may be set by the admin. If the problem is on every school Chromebook at once, it is a question for the school's IT team, not for you.

Why is Google Classroom crashing on my phone?

Usually because the app is out of date or its stored data is damaged. Update Google Classroom in the Play Store or App Store first. On Android, force stop the app and clear its cache under Settings, Apps, Classroom, Storage & cache. On iPhone, delete the app and install it again. Google says the latest app needs Android 5.0 or iOS 11 or later, and that Docs, Sheets and Slides are needed for all features. If the website works in the phone's browser, use it while you fix the app.

Will clearing my cache delete my Google Classroom work?

No. Your classes, posts and assignments are stored on Google's servers and in Google Drive, not in the browser cache. Clearing cookies and cached files only removes local copies and signs you out, so you sign in again afterwards. On an Android phone, Clear storage for the Classroom app also removes files you downloaded for offline use, but not the work you turned in. Saved passwords and bookmarks in Chrome are not touched when you leave their boxes unticked.

Why does Classroom load but pictures and files stay blank?

This is a typical sign of two signed-in accounts. Classroom may use one account while the files in Drive belong to another, so the pictures cannot load. Users in Google's forum describe exactly this: images in student work failed when the school account was the second signed-in account, at an address with /u/1/, and worked when it was the only or the first account. Sign out of all accounts and sign in with the school account only, or give the school account its own Chrome profile.

Why does Google Classroom say I can't use it with this account?

Google says this message means you signed in with an account Classroom does not accept for you, for example a work Google Workspace account. Sign out and sign in again with your school account or a personal Google Account. In the mobile app you are asked to add another account: choose the school one. If you see that your administrator has not activated Classroom, or that the service has been disabled by your admin, only the school's IT admin can turn Classroom on for your account.

Which browser works best with Google Classroom?

Google says Chrome supports all Google Workspace features, and it supports the latest Chrome version. Firefox, Safari and Microsoft Edge also work well, and Google supports their current and previous versions. Firefox and Safari lack offline access to Gmail, Calendar and Docs, which Classroom does not need for loading. Whatever you use, cookies and JavaScript must be turned on. If one browser hangs and another loads Classroom at once, the first one has a profile problem: see Fix 3 and Fix 4.

The Turn in button does nothing in Google Classroom. What can I do?

This is a different problem from the loading screen, and readers also search for it in other languages, such as the Hungarian nem adja be. Google's student help says to tell your teacher if Turn in shows an error. If an attachment cannot be turned in, copy your work into a blank document, remove the attachment, choose Make a copy, paste the work and select Turn in. For teachers with a personal account, Google adds that a full Google Drive can stop students from turning in work.

Can I get help with Google Classroom in another language?

This page is in English and covers the loading problem. Classroom itself follows the language of your Google Account: Google's help says you change it in your Google Account language settings, on the web or on your phone. The Classroom Help Center and its community forum are available in many languages, and you can choose yours at the bottom of each help page. Google's help pages are offered in Spanish too, while this page adds the checks Google spreads over several articles.
