Thunderbird is not connecting to Gmail POP server

Couple days ago my Thunderbird stopped connecting to Gmail POP server, returning an error that the server is unavailable. The Thunderbird version was way too old and didn't have OAuth2 option, so I updated to the most recent version 140.7.2esr. Nevertheless setting OAuth2 didn't help.

Then I deleted completely the Gmail account and all saved passwords related to it and created a new mail account for Gmail from scratch. But connecting is still not happening.

Receiving of cookies is enabled. The parameter javascript.enabled is set true. What else can be checked for possible cause of the authentication denial at Gmail's side?
