While running a WordPress website, it is a very common thing to come across a few errors every now and then. Errors like white screen of death, DNS probe errors or the ones related to database connection are very common. DNS probe errors can be very very annoying as they leave the users in a frozen state and they cannot get redirected to the target website. When such an error occurs, you will see a message on your screen saying dns_probe_finished_nxdomain error has occurred on this website.
At this point you must have started wondering what this error is, what are the causes and how can we fix it. In this blog, we are going to discuss every important aspect of this error.
What is this Error?
The dns probe finished nxdomain error takes place when there is an issue with your DNS. This issue can be a misconfiguration or something else. Basically, DNS stands for Domain Name Server which connects domain names with actual web servers to direct traffic on the internet. In other words, this system processes a human-friendly request and translates it into a computer-friendly IP address.
Whenever a user enters a URL in the web browser, DNS starts the process of connecting it to the IP address of the actual server. This is called DNS name resolution and a DNS recursor starts querying different nameservers to figure out the actual IP address of a server. Generally, the user is redirected to the target website but if it fails then you will receive the DNS_PROBE_FINISHED_NXDOMAIN error.
