No connection between the componenets

Hi
After a week of trying establish MQTT server I think I need your help
Running HA on Ubuntu in a docker, installed also MBS bridge in a docker but it feels as I don't really know what I'm doing. I attach here all configurations if someone please help me have a working MQTT server.

Is there any way to check that MQTT borker and the MBS-bridge are communicating with each other?

THanks

Logs from Mosquitto broker and HA are attached
