my thunderbird android app gives me the error "unable to parse tls packet header" when trying to manually configurate my email

Thunderbird för Android Kryptering

I installed thunderbird on my new Samsung A26. I tried to configure the imap connection for my email - provider is liwest.at - per their settings. the incoming mail check worked. but the outgoing mail check gives back the error "unable to parse tls packet header" I checked username and password multiple times and tried all versions of password authentication possibilities.

I googled the error but the only thing I could find was a possible mismatch in tls versions. I asked my provider about it - their customer service could not confirm with their technicians what version is in use but according to their documentation it should be tls 1.2

Have you tried TLS/SSL and STARTTLS on the SMTP server settings page to see if either works? Settings > account > sending mail > outgoing server page.

I can't access the app settings. On startup of the app it demands I either import setting (which I have nowhere to import from) or that I create an E-Mail account - during the process of creating one I get the error and am denied to get to any further settings for the app.

I was able to try to change it to STARTTLS during the account creation progress and that did work. I had not tried that since my provider explicitly stated that they use SSL/TSL
