Issue: How to fix “Your DNS server might be unavailable”

I can’t access Internet. None of the websites is loaded successfully because of the “Your DNS server might be unavailable” error. How can I fix this problem?

Solved Answer

While we all know much about the Internet, not many of its users have at least background knowledge about the Domain Name System (DNS).[1] Actually, these two definitions are inseparable from one another.

The DNS server works in the background and converts human-readable website names[2] into computer-readable numerical IP addresses.

In other words, DNS performs as a mediator between the computer and its user. We, as Internet users, use domain names to access the websites that we need, for example, the domain name of Google is google.com, so we type this domain name in the address bar and hit Enter to access the website.

However, PC does not understand the domain name as such and here’s where DNS server interpose. It determines what IP address[3] is associated with the domain name and translates it into the computer-readable code, so that the system could open the required website.

In a nutshell, we would not be able to browse the Internet without DNS server working properly. In this case, the web browser may return the “Can’t connect to website address” or similar error messages when trying to access any website. For some people, the Internet connection seems to be accessible, while the others may get the “Limited access” notification.

However, the system seldom reports the unavailable DNS server explicitly. To isolate the culprit of the lost Internet connection, the PC’s owner has to open Windows 10 Settings app -> Update and Security -> Connection Troubleshooter. Alternatively, people can get to Control Panel and run the network diagnostics there. Both ways, the scan may return the error message saying that “Your DNS server might be unavailable.”

DNS server might be unavailable due to various reasons, for example, the inappropriate DNS or network configuration, incorrect DNS address, and similar. However, it’s difficult to isolate the exact culprit why DNS server is down, crashing, restarting or not available at all, but there’s a list of applicable methods that can help to fix “Your DNS server might be unavailable” error and other DNS-related problems on Windows.

DNS server problems are extremely tiresome as they prevent people from connecting to the Internet and performing everyday tasks. Thus, DNS problems have to be addresses as soon as possible if you want to use the Internet normally.

Since one of the common DNS error causes is virus or malware infection, we would strongly recommend running a scan with a professional security program. We would recommend Reimage due to the fact that it will check for malware and scan for system’s integrities, check the system’s settings, registry entries, configurations, and other important aspects.
