Hello,  
I'm using a public broker (HiveMQ) to connect to my bluemix node-red instance, and when I publish a message from HiveMQ, it's not appearing in my output nodes (debug). I've tried messing with the port it connects over, but HiveMQ seems to require port 8000. Any suggestions as to how to prompt output?
