Swiften 3 isn't authenticating using PLAIN (with working TLS)

[lnjX]

I even have allowed PLAIN without TLS.

Swift::ClientOptions options;
options.allowPLAINWithoutTLS = true;

client->connect(options);

(after two exactly the same retrys of this, the connection just fails)

One of the problems here is probably that HipChat uses it's own XMPP extensions.

FYI: With gajim it's just working fine.

What if you will disable stream compression ?

[lnjX]

I'll try that today. Thanks.

[lnjX]

Yeah it works without compression! But shouldn't Swift/Swiften automatically recognize if stream compression works or works not?

[tfar]

Sorry. Pressed the wrong button.

I think this is going to be hard to diagnose without help from the server vendor unless you can MITM the TLS negotiation so we can get a wireshark of the compression setup.

This issue seems to have gone dead, and looks like a server compression bug. Closing until/unless we get more information to debug with.
