I was able to solve the problem. You can consider the thread as SOLVED. thank you for your help.
we are using server side certificates only.
i tested the certificate with openssl in the docker console :
openssl s_client -showcerts -servername [server] --connect [server]:8883
and saw that the certificate wasn't accepted.
Issue was a faulty system-time. i connected the module through the webinterface to a ntp-server and now everything works fine.
