Unsure what I’m doing wrong..

[Hsuser]

I have mqtt install on my unraid server and connected to node red but cannot seem to get mcsmqtt to connect to the broker.. I’m I doing something wrong? Also I noticed in the newest update that mcsmqtt can be broker less? How would I maybe just go that route to node red if that’s possible?

It looks to me as if your setup to a broker is reasonable and the mosquitto log does show a connection was made, but lost.

I did a little test with another client connecting and with mcsMQTT connecting and found the following in the mosquitto log. The other client also had a socket error when I closed down that client. This is normal behavior. For your HS case are there any errors in the HS log that may provide some clues? There is also a debug capability that may have more info that is enabled at the top of the general tab.

To use the internal broker you will remove the Broker IP from mcsMQTT setup. In node-red you will use the IP of your HS install which looks to be 172.16.16.40 in this specific case. You will first need to shut down mosquitto if it is also running on the HS computer.
