Hi,
I had the same issue on TB102. Self-Signed certificates rejected despite
having the CA installed correctly as authority. Turns out out that that
TB now wants extension "Subject Alt Names". Added that and all works
now. Seems another Google pressed issue being introduced (my Chromium
had same issues and rejected certs before I added SAN).
Thanks and regards
Goetz R Schultz

I just ran into something similar with the latest version of TB.
I updated our SSL cert for Dovecot but TB could not access my email over
port 993.
I clicked on file then get new messages for all accounts. TB popped up a
warning that the cert had an invalid/incorrect hostname and if I should
allow the exception. I allowed the exception which worked and TB is fine
now.
I only did this because my ssl cert is a wildcard for the domain but
does not explicitly list the hostname.

Sound to me, as if Thunderbird does not know the CA used to (self) sign
that server certificate.
Following the documentation at
https://community.letsencrypt.org/t/simple-guide-using-lets-encrypt-ssl-certs-with-dovecot/2921
I configured
ssl_cert = </etc/letsencrypt/live/...../fullchain.pem
ssl_key = </etc/letsencrypt/live/...../privkey.pem
to my Let's Encrypt SSL certificates and did a restart of Dovecont and
at least for one installation of Thunderbird it seems to work again
now. For the other installations I need to check later at home, but
the problem seems to be resolved.
