Socket error on client <unknown>, disconnecting

I am running OS 6.1 with mqtt addon and just noticed a huge spam load of the following messages:

1624636374: New connection from 172.30.32.2 on port 1883.
1624636374: Socket error on client <unknown>, disconnecting.
1624636494: New connection from 172.30.32.2 on port 1883.
1624636494: Socket error on client <unknown>, disconnecting.

When debugging I found out that that IP is the internal docker IP of the supervisor container running. How and why is this happening? I checked that my mqtt intergration is configured as should which it is. I also check if the node-red node is connected as should which it is.

How can I debug this even more?

Hi Nivong,
I have exactly the same issue while trying to get my Texecom2mqtt working and see the same error in my logs. Have tried everything but can’t seem to get it to connect.
