Hello there, I got a Problem with my Moska MQTT Broker. If i want to use the Broker it says, Broker is unconnected. the Debug window says the following: msg : string[73] "Error starting mosca mqtt server, cause: Error: listen EADDRINUSE :::1883" I have no idea what s wrong..

EADDRINUSE means something is already listening on port 1883 preventing your mosca instance from running.

okay, so what can I do that this port is free for the Broker?

Most likely you already have an MQTT broker running. Run the command netstat -nlp|grep 1883 to find what is using it. Perhaps Moska is already running or perhaps you have installed mosquitto or another broker.

okay, you re right, it is still running a mosquitto… with which command can I delet this?

yes i do… but don t find, what i exactly need

What OS are you running this on? How did you install mosquitto? If you already have mosquitto installed and running, why do you want to also use Mosca?

it is running on a raspberry Pi with Raspbian. …cause i trie to communicate with Node-red from my Pi and the node red from my Windows PC. And all my tries to fix this with mosquitto are just with out a result, so I tried to fix it with Mosca cause it seems beeing easier with mosca and node red…

..and i find a Topic which handle the communication as i want it, with mosca.. [image] One node-red device to ctl another node-red device General I’d imagine MQTT would be the simplest if the flows are running on different machines
