Lost Sonarr Rockon on Installed List

Was trying to add storage to my sonarr addon, didn’t succeed and Sonarr no longer shows up in the installed list of Rockons or in the list available to install. Navigating to its URL shows that Sonarr is still running. Clicking update doesn’t fix the issue and neither does rebooting or turning the Rockon service on/off.

Now it throws this error and refuses to take just about any action.

Unknown internal error doing a GET to /api/appliances?page=1&format=json&page_size=5000&count=

Solved by reinstalling and importing disk array back.
