I am using test.mosquitto.org for MQTT. It was working perfectly fine. Then i redeploy the node-red on bluemix. After that MQTT is down. It's keep on showing connecting
I have another node red instance running from Raspberry Pi it's also showing me connecting.
Have you specified a Client ID in the MQTT broker node? If so then have you got that same id in both flows? A client ID can only have one connection open at a time so if you try to connect twice it will keep flicking between the two, though I don't know if that would give quite the symptom you are seeing. On the Pi, stop node-red then start it in a terminal and see what it is saying. If you have used the same client id the simplest thing is to clear that field on one of them and node-red will automatically create a unique one for you.
