This has nothing to to with PFS. The service got disconnected since a day.

Please wait some time to see if jabber.ccc.de will come backe again or not. Noone knows...

Comment 2 Andreas Schneider 2015-10-01 08:17:28 UTC

New server is up and running, so try yourself ...

Comment 3 Andreas Schneider 2015-12-09 11:09:45 UTC

jabber.ccc.de works just fine with Pidgin but not with KTP, please try yourself ...

Comment 4 Martin Klapetek 2015-12-09 16:58:27 UTC

Can you please try connecting with Empathy and post the results?

Comment 5 Christoph Erhardt 2015-12-30 11:51:11 UTC

I did some testing on Fedora 23.

* Empathy successfully connects to jabber.ccc.de. (Side note: It constantly complains that the CAcert certificate is untrusted - even after I ticked the checkbox "Remember this choice for future connections".)
* KDE Telepathy always fails to connect: "There was a network error, check your connection". There is no warning concerning the certificate.

I'm relatively sure that the issue has nothing to do with forward secrecy. I have a secondary XMPP account on another server that deploys PFS, and KDE Telepathy has no problems connecting to that account. Maybe it's an issue with the untrusted server certificate?

Comment 6 Andreas Schneider 2017-01-05 11:01:18 UTC

Yes, seems to be an issue with CACert certificate.

Comment 7 Andreas Schneider 2017-01-05 11:05:59 UTC

Changing it to confirmed.

Comment 8 Christoph Cullmann 2024-09-18 18:12:46 UTC

Dear user, unfortunately Telepathy is no longer maintained.

Please migrate to another solution, e.g. for Jabber a possibility is Kaidan, for Matrix a candidate is NeoChat.
