Make sure that your browser is up to date. Sometimes the “Connection timed out” message can appear if your browser is out of date. Outdated #software can have compatibility issues and bugs that can cause this and other errors to appear.
The HyperText Transfer Protocol (HTTP) 408 #Request Timeout response status code means that the server would like to shut down this unused connection. It is sent on an idle connection by some #servers, even without any previous request by the client.
To fix the problem, be sure that your browser is up to date.
To Fix the ERR_CONNECTION_TIMED_OUT Error:
1. Check Your Connection. Google Chrome, Firefox, and Edge all recommend that you should check your network connection.
2. Disable Firewall and Antivirus Software Temporarily. Firewalls and antivirus software are intended to protect users and their systems.
3. Disable Proxy Settings.
4. Change DNS Servers.
