Yup

Thanks. It was due to me using a wrong port. Its working now.

Sorry for the inconvinience

Yes, also occures without the header. But I think I know the problem now: I tried to use the certificate of my host provider, which seems not to work for federation

Ok, yeah, I’m using a certiciate of my domain provider. Maybe that’s the problem … thanks! I will try to do it with letsencrypt/acme

Or do you know a similar post maybe?

Ja stimmt, Novelle trifft es eher. Die einzelnen Teile sind aber einigermaßen abgeschlossen. Man kann es also in Häppchen lesen.

Hab noch nicht für mehr als den Anfang Zeit gehabt, der klingt interessant.

Danke :)
