Offline-comunication_error

HEEELP HEEELP !! I already cleared the cache but it’s still the same :frowning:

There’s not a lot of information here.

What is your MQTT broker?

How did you setup your bridge to the MQTT broker?

Are you sure your MQTT broker is running?

and when I add something new it goes offline again :frowning:

There will be more detail in your openhab.log

Has this ever worked, or are starting out new with MQTT ?

Looks like the embedded broker is struggling because a file it uses has been trashed. Maybe that’s down to a failing SD card if you have one, or an unexpected power failure.

because if you are starting out, the advice is not to use the embedded broker.
