Difficulties connecting to the open_chat@conference.igniterealtime.org MUC

I’ve some difficulties connecting to open_chat@. I first thought that the new Openfire version does not longer process stanzas in-order. But I also see things like this in Poezio’s XML console:

i.e. a unavailable presence out of nowhere.

Yeah. I’m having (maybe other) difficulties. Something very odd is going on, and I cannot duplicate this on any other server. Are you (potentially) using nick sharing at all?

Nope, no nick sharing involved. My setup currently is a single poezio instance running in a long-living tmux session.

OK. Found another bug within PR #902, where it doesn’t strip the content namespace from stanzas coming through Websockets. I think. That causes Metre, at least, to drop the stanza (and the connection); it could do the same elsewhere.

Indeed, it does - but it also causes really weird things to happen. For example, during a MUC join, if there’s someone from a WebSocket connection in the room, you’ll get their presence replayed within jabber:client over the S2S link, which’ll terminate your connection - often throwing away the remaining stanzas. So you’ll never actually join.
