MQTT stopped working - 2024.11.2

Hi, recently updated to 2024.11.2 and now I am not getting updates and cant connect to my mqtt destination on different network. tested it from my PC and mqtt is accessible but its not working in HA.

What is happening?
In the notes there were added discovery for MQTT thats automatic which would be great. but something just broke. I was trying to figure out and test network but everything was little bit strange.

Fortunately it now connects. Did find out close to invisible and rare issue in network config and its fully fixed.
