I managed to get it online...... somehow?!

I think I managed to set MySensors gateway, but still MQTT GW in OH is offline
Make options were:

./configure --my-transport=rf24 --my-gateway=mqtt --my-controller-ip-address=127.0.0.1 --my-mqtt-publish-topic-prefix=mysensors-out --my-mqtt-subscribe-topic-prefix=mysensors-in --my-mqtt-client-id=RibaaaMQTTgw --my-debug=enable --my-mqtt-user=openhabian

Here is Mosquitto log

RibaaaMQTTgw is MySensors GW
paho45203016857 is client from org.eclipse.smarthome.mqttbroker.cfg file ( I base that conclusion on username)

Here are MySensors logs

Sorry for stupid question.
How do I check this?
I have did all steps according to
https://forum.mysensors.org/topic/9346/getting-mysensors-mqtt-gateway-working-on-openhab-2-2-stable (I did mqtt broker according to OH 2.3 requirement)
and did not manged to get MySensors MQTT Gateway online

It is RPI (NRF24L01 connected to GPIO pins)

MySensors MQTT gateway is offline.
I can not make it working .....
Here are my settings

org.eclipse.smarthome.mqttbroker.cfg

name=mosquitto
host=localhost
secure=false
port=1883
username=openhabian
retain=false
clientId=openhabRibaaa

mqtt-eventbus.cfg

broker=mosquitto

MySensors MQTT Gateway

Broker Name = mosquitto
Subscription Topic = mysensors-in
Publish Topic = mysensors-out
Enabled: "Enabled the startup check"
Enabled: "Enabled network sanity check"

Re: OpenHAB Mysensors binding 2.4: cant get mqtt gateway online

I have strange problem with MQTT:
MySensors MQTT Gateway is offline, allthough lof is at one point saying that is connected?!

Here is log:

Mosquitto log looks like it is working OK, at least to me?!
