Working with MQTT

i’m trying to work with Mqtt but got stuck, Openhab won’t show the topic state or list the items i made to give a commend or read the state. the Mqtt server is online and works.

can some one help me out, bring me to the right direction?

i have read a lot of information, conform several times if my syntax is right can’t found the problem.

It would be a lot easier to read text than looking at pictures! :slight_smile:
