I've been using Thunderbird for about 25 years with several email accounts. For the oldest of those accounts, suddenly my email will not download when I click on Get Messages. The other email accounts are unaffected. I can still send email from the affected account on Thunderbird, I just can't receive. I can get email for the affected account on Webmail. I also started having multiple Thunderbird crashes occurring, coinciding with the email download issue today. I'm running version 102.6.1 which was automatically installed on 12/21/22. I had no problems until today (12/29/22). I've tried restarting, rebooting, turning off Avast, deleting all emails on Webmail, and checking for other problem emails on Thunderbird. Any help would be appreciated.

As avast has a fairly long history of not only causing issues with mail retrieval post update but also causing program crashes, you might want to try restarting the machine is Safe mode with networking (the only reliable way to get an antivirus to actually turn off, they tend to lie about being off) and see if you are still having the same issues.

Matt, thanks for taking the time and posting the info. As it turns out, I have my own mail server and its certificate expired the day my problem occurred. So, I think Thunderbird recognized a security threat and stopped communicating with my mail server. After overriding the expired certificate, email was flowing again.
