Fixing Google Chrome Error ERR_ICANN_NAME_COLLISION error in Windows 10

If you are browsing the internet using the Google Chrome browser in your Windows 10 computer but you suddenly encounter an error message that states, “ERR_ICAN_NAME_COLLISION”, read on as this post will walk you through in fixing the problem. Here’s the full content of the error message:

“The site can’t be reached, This site on the company, organization or school intranet has the same URL as an external website. Try contacting your system administrator. ERR ICAN NAME COLLISION.”

This kind of error is caused by an error in a private namespace or a random redirection to an incorrect proxy server. There are several ways to fix this error. You can try to check the integrity of the Hosts file or check the proxy. You could also try to use the Registry Editor and apply some tweaks or remove any conflicting browser extensions or flush the DNS cache, as well as run a malware scan.

Option 1 – Try to check the integrity of the Hosts file

To check the integrity of the Hosts file, refer to the following steps:

  • You have to navigate to this path inside File Explorer: C:WindowsSystem32driversetc
  • After that, look for a file named “Hosts” and right click on it and open it with the Notepad app.
  • Next, make sure that you write the block URLs in your computer in the list and then save the file.

Note: There are times when you are logged in with administrator credentials and you may receive an error message. In such case, type “notepad” in the Start Search and right click on Notepad from the search results and then select the “Run as administrator” option. After that, open the Hosts file and make the necessary changes and save it.

Option 2 – Try to check the Proxy server

There are some users who reported that they’ve fixed the problem after they’ve disabled the use of a proxy server using the built-in way. Follow the steps below to disable proxy server.

  • Tap the Win + R keys to open the Run dialog box.
  • Then type “inetcpl.cpl” in the field and hit Enter to pull up the Internet Properties.
  • After that, go to the Connections tab and select the LAN settings.
  • From there. Uncheck the “Use a Proxy Server” option for your LAN and then make sure that the “Automatically detect settings” option is checked.

  • Now click the OK and the Apply buttons.
  • Restart your PC.

Note: If you are using a third party proxy service, you have to disable it.

Option 3 – Try to use the Registry Editor

Before you apply some registry tweaks, make sure that you create a System Restore point. Once you have that covered, follow these steps:

  • Tap the Win + R keys to open the Run utility and type “regedit” in the field and tap Enter to open the Registry Editor.
  • After that, navigate to this registry key: HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesTcpipParametersDataBasePath

  • Look for the default key and double click on it and make sure that its Value data is set as “C:WindowsSystem32driversetc”.
  • Now exit the Registry Editor and restart your computer to apply the changes made

Option 4 – Flush the DNS cache

You could also try to flush the DNS cache to fix the “ERR_ICAN_NAME_COLLISION” error. All you have to do is open Command Prompt as an administrator and then execute each one of following commands sequentially to flush the DNS cache:

  • ipconfig/release
  • ipconfig/renew
  • ipconfig/flushdns

Option 5 – Get rid of any conflicting browser extensions

  • Open Chrome and press Alt + F keys.
  • Go to More tools and click Extensions to look for any suspicious browser extensions or toolbars.
  • Click the Recycle bin and select Remove.
  • Restart Chrome and press Alt + F keys again.
  • Proceed to On Startup and mark Open a specific page or set of pages.
  • To check if the browser hijacker is still active, click Set pages, if it is active, overwrite the URL.

Note: If removing the browser extensions or toolbars didn’t work, you can also try to reset your Google Chrome browser.

  • Open Google Chrome, then tap the Alt + F keys.
  • After that, click on Settings.
  • Next, scroll down until you see the Advanced option, once you see it, click on it.
  • After clicking the Advanced option, go to the “Restore and clean up option and click on the “Restore settings to their original defaults” option to reset Google Chrome.
  • Now restart Google Chrome.

Option 6 – Run a malware scan using Windows Defender
