On our Windows computer Thunderbird has always had an issue where it would pop up a message saying "Could not connect to mail server imap.comcast.net, the connection was refused". A few hours or days would go by and Thunderbird and Comcast would talk to each other again. I finally had some time to try and debug this and (of course) I couldn't get the error to reproduce but instead I kept getting an imap timeout error. I captured the error message but it doesn't tell me why it's timing out or what to do about it.

P.S. Yes, I increased the timeout value from 100 to 300 and now it simply takes longer

Details: Windows 10 Home 22H2 Thunderbird 128.3.1esr

There is nothing in that log to indicate anything but a successful IMAP login followed by a timeout when the system is asked for mail.

My guess is you have a defective antivirus product.

If it was a router issue you would not authenticate. If it was an encryption TLS type issue, again you would not authenticate. The server is indication is has a "next mail" and provided the reference.

SO I am guessing the antivirus is intercepting the message and going off to la la land. So try disabling the mail scanner and see if that helps.
