What does ‘server DNS address could not be found’ exactly means?
Every website on the internet has a numerical IP which is associated with the human understandable domain name, this IP address is used for the packet to packet communication and if the DNS (server) which acts as the translator fails to retrieve the IP Address of the site you are trying to visit, then this error is triggered.
Generally, this issue is seen when a domain you are trying to access is down, the dns server is down or your local cache is returning an older IP address which usually happens after a change of IP Address at the server-level.
In this guide, i will walk you through the steps to address this issue – however, if the issue is due to a server misconfiguration of the site you are visiting then these methods wont help.
Method 1: Clear Host CacheYou can also clear your Host cache, which will solve the problem if it is being caused by an Extension. To clear out your cache, enter Incognito Mode in Chrome by pressing the three vertical dots in the top right of the page, and clicking ‘New Incognito Window’.
In the URL bar, enter chrome://net-internals/#dns and press Enter on your keyboard. On the screen, look for the Clear Host Cache button. Next, open up a command window by finding by pressing Start and choosing Run. In the text field, type ‘cmd’ and then enter ipconfig /flushdns.
Method 2: Update the DNSThis method has gained a lot of popularity which suggests that the user should update the DNS server to that of Google as they are more reliable. If Method 1 fails, try the DNS_PROBE_FINISHED_NXDOMAIN solution.
Method 3: Look Up IP and add to Hosts FileThis method may work or may not, since it still requires use of DNS servers to query the IP but it can provide a bit more insights into the issue – if you are still able to access other websites, then try opening the following link
Replace domain.com with the domain you cannot visit, and take note of the IP Address
Generally, all the IP’s you see should be same, but if its not then the ones mostly used is the right one (copy it).
- Click Start or Press the Windows Key (Right-Click) notepad and choose Run as Administrator
- Click File -> Open and browse to
- Choose All Files and choose Hosts and open it.
- Add the IP Address to the bottom of the file in this format
- 127.0.0.1 domain.com
- Replace 127.0.0.1 with the IP you have copied earlier and the domain with the domain you queried through the link above.
Save the file and now trying accessing the site. This will look up the route locally, before quering your DNS because we have already pointed the domain to it’s IP Address. If the site still won’t open, then it’s probably an issue with the site. You can also try opening the site from your mobile to rule out possibility of current device configuration/caches or reply in the comments below with the site name and we’ll check it for you.
