ERR_SOCKET_NOT_CONNECTED error in Google Chrome
on Windows

Hello. I started getting the error on my computer. Specifically in Chrome. ERR_SOCKET_NOT_CONNECTED is the particular code that I see or Error 15. I think it is not related to a specific site because I get this when I search on Google too. It is a very vague and random issue. Can you help me?

ERR_SOCKET_NOT_CONNECTED error in Google Chrome and other browsers is a common issue but not a problem directly related to a particular thing. It is a vague issue that can be caused by different factors, so solutions differ depending on a specific situation. Those triggers can be Socket Pools, server issues, third-party applications, malware.[ref en-1] 

The issue often is occurring when users try to get to Google websites and services on Internet Explorer or Google Chrome web browser.[ref en-2] There are a few variations of the issue because sometimes it blocks access to any websites, and other instances are related to particular sites.

In most of the scenarios, the socket on the browser is having problems and triggering these error messages. Socket pool in the browser gets corrupted, is not working properly. Flushing the sockets can solve these issues pretty easily. But when there are other reasons for this problem it might be more difficult to fix the ERR_SOCKET_NOT_CONNECTED error in Google Chrome.

Solutions can include setting changes. DNS server might not be accessible, so Chrome fails to connect. Setting the Google DNS can fix the issue. Browser storage or installation file problems also can be related to this error code on the browser. Of course, there are various other files and problems with Windows 10[ref en-3] that can lead to the failure of programs.
