    Help MQTT + Raspberry Pi

    Hi there I have installed HiveMQ but I cannot get it to work using localhost/127.0.0.1. It is giving me the error message of "Connect failed: AMQJS000I Socket closed.I cannot figure out how to fix this?

    I've never done anything with the PI or MQTT/HiveMQ, but here is my first thought:

    I'm guessing you are running HiveMQ on the Pi, but it doesn't seem to work because of the error you mentioned?

    If so, in a terminal prompt type ping 127.0.0.1

    After this try ping localhost

    If that doesn't work, try using nslookup to see if localhost resolves to 127.0.0.1

    Basically most kit is configured to treat localhost/127.0.0.1 as loopback - i.e. to be sent to the same host that is sending them rather than another device on the network.

    Sounds like this is broken for some particular reason although I have to say I have no idea what the cause may be and how to fix it. If pings are working, but your app isn't working, then maybe a firewalling issue, or your sw hasn't been bound to the correct interface?
