It feels very annoying to have your browsing experience interrupted by sudden network and connectivity issues, especially when you’re in the middle of something very important like watching your favourite movie. Nevertheless, browser crashes are seemingly common in most laptops, desktops, phones, tablets, etc. They arise due to a number of reasons and are fortunately pretty simple to identify and can be easily fixed.

In this article, we will discuss one such browser error that reads, “Server DNS address could not be found” and the different ways to fix this error. This is a step-by-step, comprehensive guide to fix the DNS Address Error and to prevent it from recurring.

First, let’s find out what exactly is a DNS Address Error and how it occurs. In very simple terms, when your browser is unable to resolve a web address into its corresponding IP address and take you to the web page you wish to go, a DNS Address Error is displayed. When two parts of the Network do not connect, you will see a DNS Error on your browser. There may be simple or complex reasons as to why this may happen. The simple issues are easily fixable. The more complex issues may be caused due to deep set problems in your network and may require some form of intervention.

 

List Of Issues That Result In a Browser DNS Address Error:

1. If the network you’re trying to connect to is down due to any reason like interrupted relay of information between servers, wrong settings, etc., you will get a DNS Error(i.e) ‘Server DNS address could not be found’

2. If your computer is prevented from accessing certain websites due to a layer of security such as a firewall, you will see a DNS Address Error on your browser.

3. If you are frequently getting a DNS Error” Server DNS address could not be found” when you try to open any and all websites, your browser have been hijacked by a Malware.

4. A DLL issue may also result in a Browser DNS Address Error.
Now that we know exactly what causes a DNS Error.

Let’s go through the troubleshooting steps one at a time to fix all the minor issues that are causing a DNS Error before you decide to dig deeper in the event that the problem still persists:

1. First of all, are you Connected to the Network?

The very first thing you should do if you encounter a DNS Error is to check whether you’re connected to the Network or not. To verify this, try to open the web page on another device connected to the same network. If you see a DNS error on the other device as well, then you need to contact your Internet Service Provider and have your Router checked.

2. Is Your Browser the Root of the Problem?

• If you are repeatedly unable to access a web page on one Browser, switch to another one. If it works, then there is something in your Browser that’s blocking you, like an Extension or proxy settings.

• Also, try switching to Incognito Mode and try again. If the problem is no longer there, then there’s definitely an extension problem.

3. Are You Allowed to Visit the Webpage?

Some networks block certain websites as a form of Content Filtering. If your computer is rigged with Parental Control, you may get a DNS Error. Proxies will get past Content Filters and Parental Controls.

4. Perform a DNS Flush:

The Flush DNS command will update the DNS records on your cache which may be causing a DNS Error due to incorrect DNS Addresses stored.

• To perform a DNS Flush, go to the Command Prompt Window on your Computer by pressing WIN+R, and typing cmd in the Run Window.

• When the Command Prompt Window opens, type the following commands one by one and hit enter:

Ipconfig/flushdns
Ipconfig/registerdns
Ipconfig/release
Ipconfig/renew
NETSH winsock reset catalog
NETSH int iPv4 reset reset.log
NETSH int iPv6 reset reset.log


Remember to check if the error is gone after running each command.

5. Switch to a different DNS Address:

First, perform an NSLOOKUP to know which DNS Server you’re connecting to. Go to the command prompt window again and type in nslookup followed by the host name. It will return the name and address of the DNS Server it is trying to connect to. To manually change this DNS Address, do the following:

• Go to the Network and Sharing Centre and click on ‘Change Adapter Settings’.

• In a new pop-up window, click on TCP/iPv4 and click on ‘Properties’.

• You will get another pop-up window where you should enter the following addresses:

Enter “208.67.222.222” in the ‘Preferred DNS Address’ box.
Enter “208.67.220.220” in the ‘Alternative DNS Address’ box.

• Click on OK.

6. Change the DNS Addresses in your Router as well:

• First, open the configuration page of your Router by entering the Router IP Address into the address bar of your browser.

Under the ‘Internet’ section, go to the ‘DNS Address’ section. Under ‘Primary’, type in “208.67.222.222” and under ‘Secondary’ type in, “208.67.220.220”. Click on Save Changes.

Now check again if you’re getting the same error. If not, you’re good to go. If yes, the problem is probably something else and you might need an extra pair of hands to help you identify the issue. The Internet is a friendly place to find more solutions. If you’re still unable to resolve the error, seek professional help. The above steps are the main troubleshooting steps you should mandatorily follow in case of a DNS Error that says server DNS address could not be found. Make sure you follow each step without missing a single one.

Here are some additional DNS Server troubleshooting steps:

• Press WIN+R on your keyboard to open the Run dialog box. Type in ‘services.msc’ and hit Enter. In the services dialog box that will pop up, find the ‘DNS Client’ service, right-click on it and select ‘Restart’.

• Plug in your Computer directly into your Router using an Ethernet cable and check.

• Restart your Computer and check.

• Perform a Virus scan on your Computer to check if there’s a hidden Virus causing all this trouble.

I hope by now you have resolved your DNS error, If not then just check your System Clock and set it as automatic to synchronize with internet timing. This should Resolve your DNS error (Server DNS address could not be found). If the problem is still there just format your system and try everything from scratch. 🙂
