What is the ERR_NAME_NOT_RESOLVED error?
The ERR_NAME_NOT_RESOLVED error occurs when your browser cannot find the website you want to visit. This is usually caused by DNS resolution issues. DNS is what changes the website name to an address that your computer understands.
DNS is very important for accessing websites on the internet. When you type in a URL, DNS helps find the website’s IP address. If DNS is not working properly, you may see the ERR_NAME_NOT_RESOLVED error.
How to identify this error in different browsers
The ERR_NAME_NOT_RESOLVED error may appear differently in each browser. Here’s how to identify it in the main browsers:
In Google Chrome
In Google Chrome, the error appears as “ERR_NAME_NOT_RESOLVED.” This indicates that Chrome was unable to locate the website’s IP address.
In Mozilla Firefox
In Mozilla Firefox, the message may be “Hmm. We’re having trouble finding that site.” Although the message is different, the problem is the same: a DNS issue.
In Microsoft Edge
In Microsoft Edge, you may see a similar message. For example, “The server’s IP address could not be found.” This indicates a DNS problem.
Why this error occurs technically
The ERR_NAME_NOT_RESOLVED error occurs due to DNS issues. This can be caused by several reasons, such as incorrect network settings, problems with the DNS server, or issues with the internet service provider.
| Cause | Description |
|---|---|
| Incorrect network settings | If the network settings are wrong, DNS will not work properly. |
| Problems with the DNS server | If the DNS server is offline or not working, you will see the ERR_NAME_NOT_RESOLVED error. |
| Problems with your internet service provider | Sometimes, the problem may be with the internet provider, affecting the DNS. |
Common causes of the error ERR_NAME_NOT_RESOLVED
When we see the ERR_NAME_NOT_RESOLVED error, it is usually due to a problem with the network or internet provider. This error can occur for a variety of reasons. These include problems with the DNS server, incorrect network settings, and problems with the internet provider.
Problems with the DNS server
A major cause of the ERR_NAME_NOT_RESOLVED error is problems with the DNS server. DNS helps convert domain names into IP addresses. If the DNS server is not working properly, the error appears.
To resolve this, it is essential to check that the DNS server is working properly. It is also important to check the DNS settings. This can be done by checking the network settings or contacting your internet service provider.
Incorrect network settings
Incorrect network settings also cause the ERR_NAME_NOT_RESOLVED error. This may be due to an incorrect IP address, subnet mask, or gateway.
To fix this, it is a good idea to check your device’s network settings. Make sure they are correct according to your internet service provider.
Basic checks before starting the solution
Before we start troubleshooting, it’s important to perform a few simple checks. These steps help pinpoint the main problem and make the solution easier.
Check if other devices are connected
Check if other devices on your network can access the internet or the website you want. If all devices have the same problem, it may be a sign that there is an error in the internet connection or router.
Test other websites and applications
Testing other websites or applications helps you determine whether the issue is specific to one website or if it is a general problem. If other websites are also not functioning, the issue may be with your connection or service provider.
Check server status
Sometimes, the problem lies with the server of the website you are trying to access. Checking the server status can provide important clues. Many websites have status pages or social media accounts that provide information about outages or maintenance.
