I’m running an ejabberd instance and it’s configured to use TLS in S2S (server to server) communications. It works perfectly fine with jabber.ccc.de, but Google’s server does not seem to like TLS.
Very awkward. First I thought it may be because of my certificate, but then I used the same as for the website (same domain, after all) and it still does not work.
No idea why it refuses to talk encrypted with Google.
