Does Artemis accept websocket connections on 61616? I'm used to ActiveMQ
5.x, which uses different ports for different protocols, and I know that
Artemis handles the protocols differently. I see from the logs that 61616
is listening for a number of protocols, and websocket is not in the list.
Is that relevant?

None of that affects the fact that the attempts to connect to the broker
via OpenWire on 61616 are failing, and we should definitely work through
that first. These comments are just for once OpenWire connections are
working, if STOMP+websockets is still not working.
