Windows 10. Thunderbird 78.12.0. Multiple Gmail accounts loaded. On the main computer, without having changed config, one of them (and only one) "Could not connect to server imap.gmail.com" It is still working on a second computer. Password has not been changed. There is no advice about what to do. Please help.

have you checked the gmail account to ensure someone has not removed the entitlement for the device to access the account? Are connections using oAuth?

I have the same configuration for all accounts in other 2 computers and on them, everything is working fine. Authentication is SSL/TLS OAuth2 in all of them. Only one of my 3 gmail accounts fails on my main computer. My main computer is the one I have the problem with. I tried deleting account and reloading it. The first day the mails reloaded on thdb, third day it stopped working again.
