Table of Contents

Hey there, future WordPress whiz! Ever tried to visit your site, only to be greeted with a frustrating “DNS Server Not Responding” error? It’s like hitting a brick wall, but don’t worry—we’ve got your back! In this post, we’ll walk you through what this error means, why it happens, and how to fix it step-by-step. Let’s dive in!

What’s a DNS, Anyway?

Imagine you want to visit your friend’s house, but you only know their name, not their address. If this example is applied to our case, even if we know the domain name of the website we need to go to, we do not know the IP address of the path to it.

Here, Domain Name System (DNS) is important for us to solve this matter. The Domain Name System (DNS) is like a magical phone book for the internet. It translates easy-to-remember domain names (like into IP addresses that computers use to find each other. When this system hiccups, you might get the dreaded “DNS Server Not Responding” error.

Why Is This Happening?

There are several reasons why you might encounter this error.

Sometimes, the problem is as simple as a shaky internet connection. A weak or intermittent internet connection can prevent your browser from communicating with the DNS server, causing this error to pop up.

Another possibility is browser problems; Your browser might be playing tricks on you. If there’s an issue with your browser’s settings or cache, it could interfere with DNS resolution.

Overprotective firewall or antivirus software can also block access, mistaking the DNS server communication for a potential threat.

Incorrect DNS server addresses are another common culprit. If the DNS settings are incorrect, your site won’t load because your computer can’t find the server to translate the domain name into an IP address.

Lastly, sometimes the problem lies within your WordPress setup. Internal DNS configuration issues within WordPress can further complicate the problem, leading to site inaccessibility and redirection issues.

1. Check Your Internet Connection

First things first—make sure your internet is working. Try visiting another website or using another device to see if the connection is stable. If everything else loads fine, then the issue is likely specific to your setup.

Example: If your favorite social media site loads, but your WordPress site doesn’t, the issue might not be with your internet connection but with your site or DNS settings.
