I've just setup a new Openfire 3.10.3 server, and clients can connect to it.
The problem I have is that when trying to integrate with Alliance Auth (https://allianceauth.com/ ) I get the following error (data anonymized, 'www.mydomain.com' replaces my domain).
[Tue Dec 22 23:48:35.678383 2015] [:error] [pid 6221] <error code="404" type="cancel">

What server is it that it cannot find? Below is the entire log for the broadcast attempt.
