network connection not working

[PieterL75]

I have openhab 4.4 with the 4.0.18 ebus-binding

openhab> bundle:list | grep -i ebus

4.4.3

My conf/services/ebus.conf looks like this

ebus:serialPort=""
ebus:hostname=192.168.123.200
ebus:ipAddress=192.168.123.200
ebus:port=5000
ebus:advancedLogging=true
ebus:networkDriver=raw
ebus:masterAddress=FF

But for some reeason the tcp connection is not being established to my adaptor.
In the logs I cannot see anything related to tcp/5000/192.168.123.200

Can you assist me with this ?
