Hi to everyone. I'm hoping someone can help. See attached picture. I have been getting this notification now and then for a few weeks now. It's getting annoying. Every time this happens, I have to manually verify my sign-in information, and it goes through without any issues. Everything stays OK for a week's time or whatever, and then, boom, I get this again. Is anyone else having this problem? Are the Thunderbird developers aware of this problem? Is there a fix I can try to stop this from happening again? Thank you very much.

I get this every couple of days on a variety of accounts with gmail.com and comcast.net. Even though I get this message the accounts are able to receive and send emails just fine. I have tried removing the accounts and re-adding them and it makes no difference.

Suddenly I can't access my mail anymore! Was using it for years. Need advice
