A few days ago, thunderbird stopped downloading downloading emails from two different frontier email accounts. I've always manually entered the passwords and now when I do this the progress bar at the bottom scrolls forever and it never connects to download the emails. Sending emails through both frontier accounts with thunderbird still functions normally, and I just experimented by adding a new gmail account to thunderbird and that is downloading emails normally. Email access through the web portal is also working normally, The issue seems to be with Thunderbird. server name: pop3.frontier.com Port: 995 user name is correct connection security: SSL/TLS authentication method: normal password Linux Mint 19.1 Cinnamon Thunderbird 102.11.0 Nothing was changed or updated on this system, it just suddenly stopped downloading emails through Thunderbird. I have tried: - resetting the desktop - resetting the routers (internet connection is fine otherwise, but worth a shot) - deleting the global-messages-db.sqlite file so it rebuilds - setting the accounts to automatically download emails - setting the accounts to save the login passwords - deleting old emails - trying to switch to OAuth2 (when I do the blue progress bar hangs) Does anyone have any other suggestions to try?
