I've been using Thunderbird for years (Windows 11 PC), and all has been working fine as recently as last night. Starting this morning, I continuously get the error message, "Login to server mail.comcast.net with user name xxx failed" (xxx not my actual account name). I've tried the "Retry" and "Enter New Password" options to no avail. I can go directly to the Comcast website, login and get my email that way, but I can't get Thunderbird to login.

To my knowledge, nothing changed between last night and today, but yet something seems to have happened. Any ideas appreciated!

And, as mysteriously as it started failing... after a day, it has just as mysteriously started working again! No idea why, perhaps it was something on the provider's end. I just hope it continues working!
