As soon as I updated to 91.3.0, Thunderbird now hangs at "Checking mail server capabilities" and I get the dancing dot in my "Inbox" tab. I can access my email using the web mail and Samsung email on my phone.

Updated to 91.3.1 and no change. "security.tls.version.min" has been set to 1

Any other suggestions?

I ran in this error on Fedora on Thunderbird 91.7.0 two days ago. I have multiple mail accounts. Some mail accounts have this issue, some not. I think that it is related to certificates. After that I deleted the certificate of a working mail account, this account also started having this problem.

I tried to find errors etc. in the console, but could not find anything that seemed related to this issue. I also tried the "security.tls.version.min" setting, but also for me it did not fix the issue.

So, also I'm asking for any suggestions.
