Hi, I’m on OH2b4 (I believe, latest on site at present) and I’m facing MQTT issues.
OH is running on Ubuntu server, and I’ve used HABmin/Paper UI to enable MQTT.
The broker is Mosquitto on the same machine, and is known good, i.e. it worked under OH1.8 and works from other clients (from phone, so I know connection details are correct; I can pub/sub from the command line also so I know it’s running).
I get the following error. In order to verify that it wasn’t my broker at fault I changed the config to point to m2m-eclipse.url=tcp://m2m.eclipse.org:1883, but i get exactly the same error, so it’s at the OH end.

Why would brokers (including the eclipse test broker) refuse my connection?
mqtt.cfg:
m2m-eclipse.url=tcp://m2m.eclipse.org:1883
mqtt-eventbus.cfg:
broker=m2m-eclipse
statePublishTopic=/openHAB/out/${item}/state
commandPublishTopic=/openHAB/out/${item}/command
stateSubscribeTopic=/openHAB/in/${item}/state
commandSubscribeTopic=/openHAB/in/${item}/command
No items are specifically configured for sending, I just want the standard eventbus logging at present. Been googling for a long time and come up short. Note that changing the port (e.g. to 1882) gives me exactly the same error message. I wondered if it was permissions, but I chowned the OH directory. Am I missing the transport 1.9 snapshot? I can’t find it on the web, and I’ve seen several MQTT troubleshooting threads that state that it is no longer needed for manual inclusion.
At a bit of a loss here.
