Mosquitto Broker searches a bridge - I don't know where to delete

Mosquitto broker
I have the problem with the Mosquitto Borker that it accesses the file under share/mosquitt/mosquitto.conf when setting Customize, but somewhere still has data about a bridge with a wrong ip in it, which is not even in the conf file. According to the conf file he should access .76, in the protocol he accesses the .75 and wants to connect to the openwb bridge. I had configured it once, but I can’t find how to delete it anymore.
Can someone help me?

Hello

In the mosquitto addon, documentation ttab it tells you how.
