I have PMS installed on a Synology NAS that contains all my media. I also have it installed on a Windows 10 pc. When I open PMS from Package Center it takes me to the web ap here: http://192.168.0.20:32400/web/index.html
I can open PMS on my pc but can’t access the NAS drive. I tried opening the web interface address above in an incognito window and it would let me. I’ve reinstalled PMS on both machines multiple times. If I could open PMS on the NAS (not the web app), I suspect I’d be able to add my media to the library.
I forgot to mention that I have had Plex accounts. The original post was in the other account. I used that one on an old laptop that used to run plex. That one fried its hard drive (overheated I think). I’ve set up a new plex account for the NAS. I tried your suggestion in the new one once everything was signed out. The old account has been deleted.
Okay now the NAS is showing up in Plex when running it from the server. It says it’s unclaimed and the Claim Server button just spins for a few minutes then reverts. It also says I have an update available.
