I'm using a self-signed server certificate. So I imported the CA of this certificate into my local CA store (see also bug#342958). When trying to connect now, I still get to see the error message: There was a problem while trying to connect mail@eliasprobst.eu - The SSL/TLS certificate received from server was not signed by a trusted certificate authority Could not connect mail@eliasprobst.eu. There was a network error, check your connection So this looks to me like the custom CA cert isn't read and/or passed to Telepathy/mission-control/gabble. The account is using gabble/jabber. Running all latest KF5 + KTP (frameworks) components from git + Qt 5.4.0. Versions of other components: net-im/telepathy-mission-control-5.16.3 net-libs/telepathy-glib-0.24.1 net-libs/telepathy-qt-0.9.5 net-voip/telepathy-gabble-0.18.3 Tried to get more information using ktp-debugger and running 'ktp-auth-handler --persist --debug', but none of them showed any useful/relevant information.
