MQTT Problem OH2.5 and Tasmota no connection

As shown on the image I easily connect to my OH 2.5 MQTT Broker with MQTT FX but no way to connect from a tasmota device.
OH2.5 on windows Zulu 8.x
Any idea?

Check you have the correct OH server IP address and password in the tasmota device.

Also try mosquitto_sub -u admin -P password -v -h -p 1883 -t ‘#’ and see what topics are provided.

where do you want me to put this line on my MQTT FX subscribe section screen? Thanks

How about putting it directly onto the command line?

Not in MQTT FX but as Opus mentioned on the command line in OH.
