Node-Red showing errors every few seconds in Mosquitto Broker log

Third party integrations Node-RED
1

Not even sure this is a problem but it doesn’t feel right.
I’m using everything through HA as integrations.
Every few seconds I get errors as shown below in the Mosquitto Broker log:

2024-02-25 23:17:09: Client NodeRed-869861a20ffa24cc-lnedf disconnected, not authorised.

I assume Mosquitto is not happy with the login credentials supplied by NR ? But the strange thing is; everything seems to work in my NR flows. I can get data from and send messages to my Zigbee devices and they all react perfectly.
I have been checking over error logs system-wide just as a house keeping exercise when I came across these errors.

Anyone have a clue what might be going on and how I might fix it ?
TIA

Go to the info tab where the debug is, the “I” button enter that number in the search. Double click the node and check it’s configuration.

You sir are a veritable genius !
Sorted !
There was no username or password set on that node.
Thanks a million.
