Mosquitto Add On will not start

Hello I’m new here. First I startet HA on RPI3 then I changed to Fujitsu ESPRIMO Q920. It works fine. But with Mosquitto I have problems.
I want to read a Tasmota device. Because I had some problems, I restored a Backup. I cleared all old entities. Than I want to install the AddOn. The Log looks fine

[14:13:59] INFO: Successfully send discovery information to Home Assistant.
[14:13:59] INFO: Successfully send service information to the Supervisor.

Than I want to start Mosquitto, but nothing happens. The status of Mosquitto is still “AddOn ist stopped”! Also the Integration says first “No communication”. Some times later I can config the Integration but the AddOn is stopped.

I didn’t know is it only a problem of the status. But I tryed all on different Laptops and browser.
