Did you recently add an lwt parameter to your mqtt.cfg configuration file, even if you’ve now removed it or commented it out? Use the config command at the openhab> prompt to inspect your configuration to see if it contains unexpected contents. Either delete the incorrect configuration, or as a stopgap, define a differently named broker in your mqtt.cfg file and reference that instead. If none of that works, please share your configuration here.

It was the lwt parameter in my mqtt.cfg. Thank you!
But how did you saw that? I didn’t notice that in the error log.

I saw the exception in the log you posted and looked at the referenced code, and it could only be reached by having an lwt configuration parameter. (I think someone could program a bot to replace me. :wink: )
