When I try te rescan my music library using the new Plex Music scanner it keeps telling me (translated from Dutch) “An internet connection is needed to scan library items. Check your connection and scan again”.
Well there is a pretty solid connection and all other services are doing fine. When I revert back to the old scanner everything is fine.
Believe me when I say “I feel your pain.” I had the exact same issue the other day on our Nvidia Shield and it didn’t matter where I initiated the scan of music files from (i.e. my windows laptop using the desktop app or directly in the client on any Nvidia Shield device (we have 3)…the end result was the same. The logs verified what I was seeing but it wasn’t true because I could still play the music any and all music files on my NAS (WD PR4100).
I tried everything I could think of like restarting the Shield devices (then validate the Shield devices reconnected to our network storage AND that the Plex Media Server started properly), restarting my laptop, restarting my NAS drives, and restarted our home network but none of those worked. I could also access all of the music files from my Windows laptop which, because of our current configuration requires an internet connection.
While I’m not a technical expert, I have enough knowledge to know that this situation just didn’t make sense and the only thing that was different from just hours earlier was that we installed the latest updates from Plex (we don’t do Auto-updates for this very reason). Out of sheer desperation, what I did was go to the Nvidia Shield device that houses our Plex Music Library and did a “Power Off” of the device (not a “Restart” because I had already validated it didn’t work). Then I physically removed the power cord and the ethernet cable from the Shield device and let it sit for about 30 seconds. I then re-connected the ethernet cable and then the power cord which automatically powered on the Shield device. As soon as the Shield was up and I saw the NAS was re-connected and the Plex Media Server started, I went into the client and saw that on my Home Screen were the new music files I had moved over shortly before. To test it I moved over another album to our Music Library, then went back to my laptop to initiate a scan which worked without issue.
I have no idea what the issue was/is, but for us just restarting the PMS and NAS didn’t work…doing a hard power down and disconnecting the ethernet cable and reconnecting them is what worked for us.
