I am using Win10, 21H2, Build 19044.1826. In the last few days I have periodically encountered the following error message when I open my browser (Firefox, version 102.0.1) to my Google home page:
"The connection has timed out

An error occurred during a connection to www.google.com.

The site could be temporarily unavailable or too busy. Try again in a few moments.
If you are unable to load any pages, check your computer’s network connection.
If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the Web."
When I click on "Try again", Google opens immediately.

This is the only site that has presented an error, so it's a merely a minor annoyance but I'm interested in learning what might be the cause and how it can be prevented.
Thank you for any insight and help!
