Plex Media Server on Synology won't run

Plex Media Server NAS & Devices
1

Synology NAS DS1019, DSM Version: 7.2.1-69057
Plex Media Server Version#: 1.29.2.6364-7000
Plex Player Version#: 1.99.0.210-2d92b948

After using Plex Media Server on a Synology NAS DS1019 for 4+ years without any major issues, I’ve been fighting various issues with this for about a week now. My Plex is basically DOWN, as my Plex media server is unreachable. I was initially getting 500 errors, despite the Plex Media Server showing as “running” in Synology. After implementing a port forwarding rule on my Verizon Fios router, and re-installing Plex Media Server AGAIN (this time using the “Claim Code” approach to try to “re-claim” my server, what I now see is that Plex “tries” to run, but then stops.

I pulled the latest Plex Media Server log, and there appear to be references in there to failed database migrations…??

Any guidance would be appreciated, because Plex is effectively dead for me right now, as my server is offline…
Thanks!

Were you previously running a 1.40 release?

If so, you cannot directly fall back to 1.29.2 due to database changes.

You will need to install the current public or beta release.

If you see any “503 maintenance” messages in Plex Web, wait for the database maintenance to finish. Refresh the web page every 5 - 10 minutes. It will not update automatically.

@FordGuy61 - Thank you so much, that was indeed the issue.

I did upgrade last week, after seeing a new server update was available via the player app…but I didn’t really pay attention to what version it was.

After all the trouble started, in the course of troubleshooting, I have since uninstalled/reinstalled the Plex Media Server (via the Synology NAS interface) multiple times — and I had just assumed that would be grabbing the latest version…
But…apparently not? Now that I’m back on 1.40, it’s back up.

Thanks again!
