All I just migrated to the latest openhabe image.I just found out that the new mosquitto server does not allow anomymous connection and so I did not got a connection to my ems heating system.
I added the following to the server code to: /etc/mosquitto/conf.d/local.conf
might be it helps others or it is already in.
Cheers
