Start with conventional solutions for this Chrome error. Perform the following steps in this particular order:
Clear Google Chrome's cache and cookies. A corrupted cookie or cache file may cause this error to show up. Clear your history, cache and cookies from the "Clear Browser Data..." menu on the Settings page.
Make sure you have unusual toolbars, extensions, viruses or malware. Many malware applications run in the background and prevent Chrome or other web browsers from connecting to external web servers. Uninstall them & use Windows Defender to do a quick/full system scan.
Check/adjust your antivirus and internet firewall settings. Firewall rules (manually or automatically activated) can block incoming and/or outgoing connections for specific ports or applications. Check your antivirus software and/or Windows Firewall settings to make sure that Google Chrome or Ports 80 and 8080 are not blocked in any way.
Restart your computer, open Chrome and try again. If the error persists move on to clearing your DNS resolver cache:
Open your command prompt as Administrator.
In your Start Menu, find "Command Prompt", Right-click on the menu item, and click "Run as administrator".
Or, in the Start Menu Search box, type "cmd", then press CTRL+SHIFT+ENTER to run it as Administrator.
Run the following commands in this order (to run each command, press ENTER after typing it):
ipconfig /all
ipconfig /flushdns
ipconfig /renew
netsh int ip set dns
netsh winsock reset
ipconfig /release
Restart your computer, open Chrome and try again. If the error still exists, you have one final option - reinstalling Chrome and starting fresh. This will reset all the remaining variables that may be causing this error:
Uninstall Google Chrome using "Add/Remove Programs" or "Programs & Features" from your Control Panel.
Delete all crashreport subfolders. You will find them under C:\Users\%your_name%\AppData\Local\Google\
Reinstall Google Chrome. Download the latest version of Chrome Browser and install it.
Restart your computer, open Chrome and try again. It should work now.
