Unable to test Mosquitto broker [message #1804222]

I'm totally new to all this but I have Mosquitto running in a Docker container on a Raspberry Pi. Portainer reports "Running for 10 hours". I opened a terminal on my main PC (Linux Mint), ssh'd into the RPi , and ran mosquitto_sub -d -t testTopic
It returns:
Client mosqsub/6490-MicroSrv-P sending CONNECT
Client mosqsub/6490-MicroSrv-P received CONNACK
Connection Refused: not authorised.

I suspect this is caused by the fact that, after installing the client, at no point did I specify the username and password I setup when installing the broker - but I have no idea how/where to do that.

I really just want to test/confirm that the broker is running/working. If there's a better way, please let me know.

Sorry for the delay replying, I don't monitor this forum much.

If you installed the eclipse-mosquitto docker image then by default it is configured without authentication, you have to then set that up yourself. If you haven't configured authentication then I don't know what the problem is right now. Did you use the eclipse-mosquitto image, or a different one?
