Problem with IMAP connection with new Thunderbird 78.2.2

more options

I automatically upgraded to new version of Thunderbird 78.2.2 yesterday morning, and from that moment I can't login to my imap account. (I tried to connect using old version from another machine and it works.) I migrated all enigmail keys into new version (as suggested) and I can see that my old messages are decrypted properly.

Does anyone have a similar problem?

I use Connection Security: SSL/TLS and Authentication Method: Kerberos / GSSAPI

I have no idea where to look.

Regards, Bosko

Do you also use a self-signed certificate for SSL/TLS?

We have a separate keys server for gpg (in our company) and I think SSL keys are also created by out IT team (that could also expire at some time, I'm not sure). I can read my emails on iPad without problems or any extra steps (but without encryption because IPad doesn't have that integrated)... Since I'm using VPN (on laptop), I changed Connection Security to None, and now it can connect and get emails. The problem is somewhere in this SSL/TLS part...

Thunderbird verifies SLL certificates... that is the query OSCP responders option in options/ Privacy and security. But the most issues with 78 have come from mail servers that have not updated to TLS V1.2 or later given 1.1 and earlier have been disallowed.

I did some IMAP logging using some batch file containing:

set MOZ_LOG=IMAP:5,timestamp set MOZ_LOG_FILE=%APPDATA%\Thunderbird\Profiles\imap.log set NSPR_LOG_MODULES=IMAP:5,timestamp set NSPR_LOG_FILE=%APPDATA%\Thunderbird\Profiles\imap.log "%ProgramFiles(x86)%\Mozilla Thunderbird\thunderbird.exe"

after looking at the log, I can see some lines containing "clearing IMAP_CONNECTION_IS_OPEN - rv = 805a2f9e" (like return value = error code) and this block looks like:
