I deleted my dvr from plex and now I have the problem, that I can not re-add the device again, due to the fact that it does not show up anymore. Even with searching the IP:PORT.
My issue is very similar to this one:
I use ubuntu linux and a network dvb-c tuner.
I already tried to delete my hole database from “Library/Application Support/Plex Media Server/Plug-in Support/Databases”. But I still got the same issue.
I really would appreciate any hint on how to fix this.
