Generally, you will see this error when you cannot open a website. The error technically means that the name cannot be resolved. There are various reasons for this error to pop up; and in general, the error may be a result of a misconfiguration on your computer or router OR it could be an issue with the website you’re trying to visit which may be down. There are two possible scenarios, it can be an issue from the website’s DNS or it can be an issue from your Network. Check to see which one is applicable to you and follow the steps accordingly.

If this is happening on your own website

When you set up your website, you get hosting with it or you buy it from a different hosting provider. When you get the hosting, you are given name servers, that should be updated with the Domain Register. For example, appuals.com is registered with GoDaddy and hosted with CloudFlare, Cloudflare, gave us their nameservers, which we’ve updated at GoDaddy. Here’s an example image of another site, that is registered with GoDaddy but has BlueHost as their hosting provider. If the hosting was with GoDaddy, then I may not have had to update the nameservers. Because usually, GoDaddy does it by themselves. So what you need to ensure is that your name servers are properly updated, and you are using the nameservers given to you by your hosting provider. If you’re not sure about this, you can check the settings by going to intodns.com/your-domain-name.com. If just your site isn’t working, and all other sites are you can see what the nslookup reports from Command Prompt in Method 1.

Check if the website is working

If you can’t able to access a website it’s not clear If the issue is from your client or from the website itself. You will have to check if the website is responding to your computer correctly, to check if the servers are working fine you will have to follow these steps:- If it doesn’t return a Valid IP Address, or if tells that the domain doesn’t exist, or any other error then it’s most likely an issue with the website. If you are the owner of the website you must check with your host in order to resolve this issue. However, if you aren’t the owner of the website and visiting the website we suggest you wait and try again later to check if the issue is resolved. If you were getting the Valid IP Address and the website is working fine you can follow the methods below.

Change your DNS Server

We can try to resolve your issue by using a Public DNS such as Google’s DNS or Cloudfare’s DNS, using a Public DNS will narrow down the problem, make sure to follow these steps: Type the following command to refresh DNS Servers on your Computer:- Check if the issue persists. If it still persists we can try resetting the DNS Cache on our Google Chrome, follow the methods below.

Change your DNS (MacOS)

If you have a MAC then you can try this method to change the DNS, follow these steps:

Clear Chrome’s Host Cache

Clearing the DNS Host cache of your Google Chrome client can help you with this issue as well. Your Google Chrome client holds a record of DNS entries to save looking them up every time which reduces the loading time of the website but sometimes bad cache can give you errors such as ERR_NAME_NOT_RESOLVED and ERR_CONNECTION_RESET. You can easily clear your Google Chrome’s cache, follow the steps below:

Disable the “Preload Pages” option

This is almost identical to Chrome’s host cache option. However, the method above only clears the cache and it doesn’t prevent websites to store them again. This option will prevent Websites to keep their DNS cache so the next time you will visit a website it will load a little bit slower but it should show any errors. Follow these steps below to disable the “Preload Pages” option.

Reset your Network Configuration

In this method, We will reset all of our Network Settings to remove every incorrect network settings possibly because of Third-party programs, and to clear any corrupted DNS data or cache, you will have to reset your network settings and get a new IP address assigned from your router. This method will ensure that you have default Network settings set on your PC. This method will narrow down the problem or potentially fix it. To reset your Network Settings properly, Follow these steps below: Check to see if the issue persists.

Other Workarounds

Unfortunately, if none of the methods above worked for you, you will have to try using another browser. If the website is working fine on another browser we highly suggest you try uninstalling and reinstalling Google Chrome. If the website isn’t working on your other browser as well then we really suggest you try contacting your ISP and explain this problem to him. Additionally, you can try using a VPN we personally suggest you try out CyberGhost from (here). If using a VPN works for you and you can access the website just fine, your IP address might be blocked.
