Error503 MQTT


I’m migrating form Openhab1 to OH2, I’m trying to install MQTT Binding but I get ( and every other things that I try to install trough Paper UI) Error503 Jersey, What is wrong?

Re-installed everything??? Really?

503 should be a temporary issue:

If the problem (either the webserver, your internet connection or your network) has not been solved by now that should do the trick.

It’s not that hard, make a backup first, reinstall and put your config files back in:

Your explanation is pretty sparce. Not much to go with.
Reinstalling is the solution know to work. For everything else you need to give more details.
In general I’d say restart openHAB and look at the openhab.log to understand what’s going on.
