Fails to establish STARTTLS connection #4097

Closed paulmenzel closed 1 year ago

paulmenzel commented 1 year ago

This setup worked for months, but something broke after changing something in the distribution or updating ejabberd. Before starting to bisect all different components, can you see what is going wrong?

Environment

Neustradamus commented 1 year ago

@paulmenzel: It has been closed?

paulmenzel commented 1 year ago

Yes, as my problem was solved.

licaon-kter commented 1 year ago

@paulmenzel but how? :))

paulmenzel commented 1 year ago

By doing, what @prefiks suggested: passing the switch -xmpphost. openssl s_client -connect xmpp.molgen.mpg.de:5222 </dev/null -starttls xmpp -xmpphost molgen.mpg.de works for my setup.
