How to Fix DNS Server Not Responding Problem

The domain name server, also known as the DNS server, sometimes stops responding, which may make it hard to open websites or web pages. There are so many ways you can fix the DNS server not responding.

You can try to establish the connection with a different device, consider using a different internet browser, try to power cycle the router, make sure you use an ethernet cable to connect the router to your computer, remove extra connections by disabling them, clear all the DNS cache and many more. These are some of the things that you can try on your own to fix this issue.

Proccess of Fix DNS Server Not Responding Problem

1)Try to Connect Using a Different Device

If you are able to connect other devices at home to the network, then that means there is some problem with the primary device that you were trying to connect and the problem isn't occurring because of the router.

If you are not able to connect with another device, then there may or may not be an issue with the router. If you are having issues with a particular website, then you can access that site using mobile data. If you are not able to access the website, then that means the website is the cause of the problem. 

2) Try Using Another Internet Browser

Another way to check DNS connection is to use a different internet browser. You can use Google Chrome or Mozilla Firefox and try to connect to the internet.

In case you still encounter issues, then that means browser issues weren't leading to DNS server not responding issues. In case the problem gets fixed by using another internet browser, then uninstall and reinstall the browser that you were using earlier. 

3) Power Cycle Your Router and Modem

By performing this method, your router's cache will get cleared and all your DNS issues will get resolved.

Below are the steps that you need to carry out to perform a power cycle. 

Step 1: Disconnect the power cable of your router and modem. 

Step 2: Let your router and modem remain disconnected for 30 seconds. 

Step 3: Reconnect your modem device and wait for it to come online. 

4) Try Connecting Your Router to the Computer Through Ethernet

If you are still not able to connect to the internet by using an ethernet connection, then it is highly likely that the problem resides in your router and you must reset it. 

There is also a chance that there is some issue with the DNS that is leading to this problem. 

5) Disable Extra Connections

Below are the simple steps that you need to follow in order to disable the extra connection.

• Launch the network setting on your computer. To do so, you need to launch the Start menu and then go to Settings. After that, select the option f Network and Internet. After that, select Change adapter options. 
• Check for extra connections. If you find that there are extra connections that you are not connected to presently, then you must remove them immediately. This includes wireless and Bluetooth connections. The DNS issue can also arise because of the "Microsoft Virtual Wi-Fi Miniport adapter". 
• Click on the extra connection to select it. On Windows, every icon on the page represents a connection. If you are using Mac, then you will find connections at the at left of your Window. 
• Now, remove the connection. In order to remove a connection, disable the network device on top of your window. Mac users need to select the - sign at the end of the network window. 
• After that, try to visit a webpage. If you are able to open a page, then that means your problem is fixed. 

6) Try Flushing the DNS Cache

• Enter Terminal there. Now, the Spotlight will start searching for Terminal on your Mac.

• After that, enter the command "sudo killall -HUP mDNSResponder" and select return. This will launch the MacOS DNS process. You will also be required to enter the admin password before you move ahead. 
• Restart the browser. This will refresh the browser cache and your issue will get resolved.
