After upgrading from V2.5 to 3 my mqtt broker isn’t working anymore.
io.netty.channel.AbstractChannel$AnnotatedConnectException: Connection refused: localhost/127.0.0.1:1883
My guess is, that there is a problem connecting to mosquitto. But the service is running. (Checked service status)
Probably the credentials are wrong. Unfortunatly i forgot the username/password I set in those days, so I tried so set it new. But how? Internet tells me to use mosquitto_passwd, but this does not exist in mosquitto 3.1 which OH installed during upgrade.
Any suggesstions? Uninstall and reinstall? Whats the best way to do this?
