How to Fix Error ERR_NAME_NOT_RESOLVED Error on Google Chrome

I’m sure all of us have come across this problem before: trying to access a website and being met with a white screen and words ‘This webpage is not available’, as well as ‘ERR_NAME_NOT_RESOLVED’. This error will block your access to the website and only give you the option to ‘Reload’, but it’s sort of redundant at that point.
This error occurs when your DNS (Domain Name Server) address is blocked.
In this article you can find possible solutions for this error.

FIX #1: – Try deleting browser cookies.

Browser or HTTP cookies are tiny bits of stored on your computer that are used when browsing a particular website. Sometimes they block your DNS address, which then results in ‘ERR_NAME_NOT_RESOLVED’ error.

To fix this in Google Chrome, type ‘chrome://settings/clearBrowserData’ in the address bar or go to ‘Settings’. Then select ‘Advanced’ at the bottom of the page, find ‘Clear Browsing Data’ and click on it. Select ‘Cookies and Other Sites and Plugin Data’, then ‘Clear Browsing Data’.

Afterwards enter chrome://net-internals/#dns again into address bar and click Clear host cache.

Try accessing the website again and see if the error is still there.

FIX #2: – ‘Flush and Renew’ your DNS.

Open the Start Menu by clicking on the Windows key, or Start Button. Type in ‘command prompt’ and when the app shows up, right-click it and select ‘Run as Administrator’. Remember that it’s important to choose to run it ‘As Administrator’, otherwise it won’t work. Press ‘Ok’. When a black-colored command window pops up, type in these three lines. After you type each line, press ‘Enter’, wait for the computer to process it, then proceed to type the next one.

ipconfig /flushdns

ipconfig /renew

ipconfig /registerdns

Close the window and restart your system. Check if this solved the issue.

FIX #3: – Switch your DNS address to a public one.

This is also one of the common solutions to ‘ERR_NAME_NOT_RESOLVED’. I suggest switching your existing DNS address to an open Google DNS address. Open the Control Panel by going to the Start Menu and clicking on it or pressing the Windows key and ‘R’ together, then typing ‘control’ in the dialogue box. When you open the Control Panel,

  1. Select ‘Network and Sharing Center’.
  2. On the left part, click on ‘Change Adapter Settings’.Change Adapter Settings
  3. Find the network that you are connected to at the moment, then right-click it and select ‘Properties’.network connectins
  4. In the ‘Networking’ tab, select ‘Internet Protocol Version 4 (TCP/IPv4)’, then ‘Properties’ again.ipv4 adapter properties
  5. In the ‘General’ tab, check ‘Use the following DNS server addresses’.
  6. For ‘Preferred DNS Server’ type ‘’ and for ‘Alternate DNS Server’ type ‘’. Press ‘OK’.ipv4 google

See if you the error still occurs.

FIX #4: – Disable your Firewall security system.

Your security system might be preventing you from entering a webpage, or internet in general, thus causing errors with the DNS address. Check whether there are some issues with your Firewall, or even try disabling it. This might resolve the error.

FIX #5: – Try unplugging your router.

There might be connection problems with your router. Switch off and unplug the power cable from your router. Wait a few minutes, then plug it back in. Again, check if the error ‘ERR_NAME_NOT_RESOLVED’ is still blocking your access.

Hopefully these were helpful, but in case none of these suggestions worked for you, you should reach out to the company that produced your router, since it may be a hardware problem that’s causing the error.
