Cannot connect "no case clause matching stream:features"

[dhanson358]

Not sure where the issue is, if it's in this module, in hedwig-xmpp, or if it's just a problem with configuration.

Followed the README and have configured like this:

config :sln_halbot, SlnHalbot.Robot,
  adapter: Hedwig.Adapters.HipChat,
  name: "Halbot",
  aka: "!",
  jid: "215754_2680719@chat.hipchat.com",
  password: "<omitted>",
  rooms: [
    {"215754_software_dev@conf.hipchat.com", []}
  ],
  responders: [
    {Hedwig.Responders.Help, []},
    {Hedwig.Responders.Panzy, []},
    {Hedwig.Responders.GreatSuccess, []},
    {Hedwig.Responders.ShipIt, []}
  ]

When I run 'mix phoenix.start' or 'mix run --no-halt' I get this output & error:

It just keeps repeating this every few seconds as it retries

Any ideas?

Hmm, I'll see if I can trigger the issue on my end; unfortunately I haven't seen it while working with our internal HipChat server, but I can set up a cloud account and try it out.

After digging a bit more, it looks like this may be an issue with the Romeo project (or some misconfiguration):

@dhanson358 can you see which version of romeo is getting pulled into your project? You may need to lock it down to 0.4.0 because hedwig_hipchat has not be updated to work with romeo v0.5.0

[dhanson358]

I tried both 0.4.0 and 0.5.0. Same issue.

[dhanson358]

I played with it some this morning, and I think what's happening is that Romeo is sending the "auth" request, but the next incoming message it gets is NOT the ack of the "auth", but an unrelated "stream:features" message. So it's trying to filter stream:features through it's authentication check routine, and it just doesn't match up.

[dhanson358]

This looks like it's now fixed in romeo master, so once that gets rolled into a release, updating the dependency in the mix.exs should take care of it.
