How To Fix DNS Server Unavailable Complete Guide will be described in this article. All domain names for the websites you’ve visited are stored on the Domain Name System or DNS server. Well, when you search for a domain name in a web browser, your router forwards the request to a DNS server. If the domain name of the respective site has been saved, it returns the corresponding IP address. This significantly speeds up the loading process for those sites. Even though this process is excellent, it is not uncommon for the DNS server to occasionally fail to establish a link. In this case, troubleshooting your web browser will frequently result in a ‘DNS server not responding’ error. This error could appear on your screen due to a variety of factors. The most obvious is the possibility that the server itself is currently down. Fortunately, this DNS Server Unavailable problem is often accompanied by a few simple solutions.

How To Fix DNS Server Unavailable?
Have you ever got an error message stating that the DNS server is unavailable? These issues can be resolved by changing browsers, fiddling with some firewall settings, or rebooting your router. Well, It will be your responsibility to determine the cause of the problem and then correct it.
Use a other browser to access the web pages you’re attempting to open. If you get the error while using Mozilla Firefox, try switching to Microsoft Edge or Google Chrome. Then, if the problem continues, we can test other devices. To ensure the problem isn’t due to hardware failures, try opening a webpage on the same network with a mobile device. It would also be useful to attempt connecting to the exact web pages using your data plan to determine if the problem is, in fact, with the DNS server. After you’ve gone through all of these steps, reboot your router. If the “DNS server unavailable” error persists, we must try a few more effective methods.
Flushing Your DNS (MacOS)
On a Mac, you can flush the DNS. The method you use will differ slightly depending on the version of Mac your computer is running. Often, all that’s required is a change in the syntax used during the process.
- Open a Finder window and/or navigate to Applications, Utilities, and the Terminal.
- Enter the following syntax for the macOS version you’re currently using.
- Press the Return key once more, enter your password, and then press the Return key again.
- Before exiting the Terminal, listen for an audio alert indicating a successful DNS flush.
A few extra steps will be required to flush out the MacOS X cache fully. In addition to the previous steps, you must flush both the MDNS and UDNS caches. Execute the following commands before exiting the Terminal.
- Run sudo discoveryutil mdnsflushcache to flush the MDNS cache.
- Run sudo discoveryutil udnsflushcaches to clear the UDNS cache.
Flushing Your DNS (Windows)

Remove Multiple Antiviruses
“There is no such thing as too much protection.” This may be true in the real world, but in the world of technology, having many antivirus programs installed on the same PC can reduce the level of protection. Check to see if you’ve two or more antivirus programs running simultaneously, as this could be the source of the DNS problem. After you have disabled all additional programs, reboot your system, and the problem should be resolved. To help defend yourself against unwanted malware attacks, ensure that you only run a single software program in the future. This improves security and may help you avoid more DNS server errors.
