c2s port listener cannot handle starttls_required and zlib enabled at the same time:
https://support.process-one.net/browse/EJAB-1118 I beleive this is your case, Christoph. So try to disable zlib in the meanwhile. Since ejabberd did not support STARTTLS+compression at the same time before 2.1.0, disabling zlib in your case should not break anything. -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
