I don’t have any experience with MQTT client of nodered but the important things to pay attention to are:
enable TLS (not sure how node red validates the certificate chain?)
port is 8883
provide a client ID (some unique identifier to identify your MQTT client)
provide a username (realm:<SERVICE_USER_CLIENT_ID>)
provider a password (<SERVICE_USER_SECRET>)
You can always look at the docker logs of manager container for any potential clues…might need to provide a custom logging.properties if you don’t see anything of interest by default.
Your config looks sensible; if you have OpenRemote generating domain SSL certificates then nodered should be able to verify server certificate using standard CA root certificates.
Maybe unchecking the Verify server certificate option will just allow nodered to accept the OpenRemote certificate to prove things are working?
Would like to check whether there is any breakthrough on this?
I’m facing the same challenge and can’t connect to localhost port:8883
I have no idea where to find the certificate, private key and CA certificate to upload on Node Red.
