Panic: file smtp-client-connection.c: line 1212 (smtp_client_connection_established): assertion failed: (!conn->connect_succeeded)

Hello,

after migrating from self-compiled Dovecot 2.3.3 to Dovecot 2.3.8 from
the repository (Ubuntu 18.04 LTS "Bionic" packages) I have issues with
the submission service. If I send an email, it will not be forwarded
and I get the following error message:

Does somebody has any idea? The problem has been taking me months, now
I want to finally update to the current version.

Can you provide doveconf -n?

Also, are you having this problem in 2.3.3 or just 2.3.8?

Panic: file smtp-client-connection.c: line 1212 (smtp_client_connection_established): assertion failed: (!conn->connect_succeeded)

Hello Aki,
I have this problem just with 2.3.8, my self-compiled 2.3.3 works fine.
I have previously tried to update from 2.3.3 to higher versions
(possibly 2.3.5 or so), but always had this error, which is why I am
always back to 2.3.3.
Configuration is exactly the same.
Here my output from "doveconf -n":
