Update 1.41.6.9685 - Libraries Invisible / 404! Remote Access Issue

Server Version#: 1.41.6.9685-72009685
Player Version#:

SOLUTION: Rolled back both the syno server and mac to the previous stable builds and both local and remote access are restored and no longer reset every morning. Links are below via @ChuckPa the KING.

I run two servers (one primary and a backup on a separate machine). I updated them both this weekend. I noticed this evening that only the primary (via synology 7.2.2) was visible via plex.tv. Plex app showed only the primary though plexAMP showed both correctly. I relaunched Plex media server on the backup (macOS) and saw that that remote share was disabled (it had been previously enabled). I renabled it, refreshed plex.tv in browser, and got a “404, this page may have been deleted” error from the primary server. Primary server was then totally invisible on every device / app (like the backup had been). All of my previously pinned libraries (the primary and backup) were now unpinned from plex.tv. Only the backup was available. I restarted plex media server on the primary, remote sharing was now disabled, I re-enabled, then only the primary server was available (across all apps at this point).

If anyone has a link to either previous version (for Mac or Synology 7.2.2) I would love to get things up and running again.

Apologies Chuck and friends, but I don’t remember how to get the logs from Synology etc. Thanks in advance.

EDIT 1: now it looks like Remote Access to the primary server (Synology) is also down. I’ve tried manually specifying public port 32400 and doing it automatically but no dice.

EDIT 2: Okay several days in. A consistent pattern has emerged!

Regardless of connectivity the previous day, every morning the Synology-based libraries are once again invisible / 404’d on Plex.tv, the Plex mobile app (iOS), PlexAMP, and Prologue. Mac-based libraries are visible on some apps (Prologue, for example, says it is connected) but always unreachable with varying error codes and no playback.

When I initially log into Plex Media Server on either device, I can see both servers and all libraries. I also see a green checkmark by remote access (which is obviously not true, as there is no access at all). If I engage with remote access controls at all (either disabling and re-enabling, or manually specifying the port), whichever server I’m not currently on disappears from PMS. The libraries 404 and the server settings and activity icons are gone. The server who’s PMS I’m on now says " Not available outside your network " in remote access regardless of what I do with the controls (manually specifying or disabling and re-enabling).

At this point, for LOCAL devices, when I refresh plex.tv or the plex apps, whichever server I manually specified the port for is now fully visible, with correct libraries (unpinned, but there) and no playback issues. Remote devices show the same errored out mac-based backup server libraries if any, ei: no change has occured for remote devices.

Here’s the funny part: If I log into PMS on the other device, exact same situation plays out. All libraries are visible on PMS, both servers are visible, whichever server I’m logged into shows green remote access. When I do anything to the remote access controls, it once again erases visibility of the other server, flags “not available outside of your network” and local devices switch from showing the first server I reset to the second one. I can flip flop them like this ad nauseum.

HOWEVER: regardless of which server I last set to “active” for local devices, the following morning it has reset to the initial state: only the Mac based libraries are available if at all on local devices, but no playback works.

I would LOVE a link to the previous PMS server builds for Synology 7.2.2 and macOS if anyone has them. Thanks!

EDIT 3: Day 4 identical behavior as days 2 & 3.

@ChuckPA, any ideas on this boss?

Hoss,

Do me a favor?

  1. Recreate whatever you can so the errors are fresh in the logs on the SYNO
  2. After you’ve done that
  3. STOP Plex in Package Center
  4. Open FileStation
  5. Go: PlexMediaServer/AppData/Plex Media Server
  6. Right-click “Logs” → Compress to Logs.zip
  7. Download the ZIP then upload/attach here.
  8. Lemme see :smiling_face_with_horns:

@ChuckPa thanks for coming to my rescue (again).

Logs are 8.5 Mbs, max upload size is 8, here’s a google drive link with the zip folder in it >>> https://drive.google.com/drive/folders/13pBaU5vaAqahwuIvZezq5CzL8W5ijhIR?usp=drive_link

Survey suggests the daily reset happens around midnight, because that’s when the plex app on the Xbox flagged the missing server per the wife (I was asleep at the time).

When I woke up, day 5 was playing out the same as 2 - 4.

Refreshed PMS via browser and everything looked the same. Went to Synology and closed the app, grabbed the logs.

Let me know if there’s anything else I can do :- )

@BobbyThomson

Thanks for the logs.

Toad is being stubborn. lol

Would you please do the following:

  1. Stop PMS
  2. Wait a minute
  3. Start PMS
  4. Let it sit 2 minutes
  5. Stop PMS
  6. This time, go into the “Logs” directory
  7. Right-click “Plex Media Server.log” and Compress to ZIP like you did last time
    – Going to grab this one file.
  8. Download then attach here for me (it will be a tiny file)

Some days the Toad giveth. Today is not one of those days.

I think this is what you’re looking for:
Plex Media Server.zip (67.0 KB)

For safety, I also zipped these numbered “Plex Media Server” logs from the folder as well.
Plex Media Server.Numbered Logs.zip (4.1 MB)

If I’m wrong (which is likely given my track record) feel free to give me a call at (484) 264-5054 and we can try it that way.

Thanks

Thanks.

This confirms your port forwarding isn’t making it inbound. ( 0 = Fail )

Remote Access into a Syno is always “fun” to troubleshoot.

  1. In Control Panel - Security,. is the firewall enabled ? (most of us disable it)
  2. How do you normally define / configure your remote access ?

Firewall on both Syno and mac are not enabled (never has been).

Remote access has been a tricky one due to AT&T… I shant say. Before the update I had both the Syno and Mac OS (which is also experiencing this issue since the most recent update), manually specified port 32400, which generally (due to AT&T hardware unfriendliness) resulted in an indirect connection for remote access. No harm no foul, if it works it works. Now, regardless of manual or auto, it flags “Not available outside your network.” That’s ditto for the Mac PMS.

I also wonder why whole thing resets every day. Hope you like a good mystery.

Anybody over there have access to the last set of stable builds before this one? Would love to test if a rollback on the Syno & Mac solves it. Just what I get for keeping my downloads folder clean.

Usually a good idea to keep one or two known good around
They are only 80 MB

Just restarted the Mac (backup) server, this time specifying port 32401 (the syno is on 32400) to see if they could coexist but on different ports (before the mac either ran using the auto connection or on 32400). Same behavior as reported above, the Syno 404’d libraries flagged as deleted or “you don’t have access”. I shut down PMS on the syno have have attached the logs here:

Logs_RestartedMacSynoNow404.zip (5.0 MB)

Restarted the syno PMS after grabbing these logs, on a whim I refreshed Plex.tv (not the PMS interface), and low and behold BOTH servers were visible (for the first time since the update). However, when I tried to play anything from the Mac server, I get the playback error: “Please check that the file exists and the necessary drive is mounted.” The restarted Syno server content plays correctly.

You’re a gentleman and a scholar.

Squaller ?

You can also run my DBRepair on the box just for sanity sake if you want

Okay good news bad news.

Deleted and reinstalled Syno server using the provided rollback. Restarted, launched PMS for safety, manually specified port, I now have remote access to it! Tested with VPN on computer via plex.tv and on data on mobile plex app and on prologue on data. Indirect connection (if it works it works), but it’s there!

Followup good news: the Backup (mac) server is now visible fully on the syno’s PMS and on devices in general.

Bad news: still no playback (local or remote) from the mac server. I do get a new playback error from the mac when attempting local access: “conversion failed. The transcoder exited due to an error”

Why the VPN ?

You don’t need a VPN to talk from PC on LAN → Syno on same LAN.

Can you enlighten ?

Is your LAN not RFC-1918 compliant ?

Apologies for the confusion. I turned on the VPN on my desktop only after re-installing the rollback on the syno to simulate remote access to syno server via Plex Windows App and plex.tv as a second check (in addition to attempting via using data on the phone) to ensure remote access was actually working, which it is!

Now I just gotta find a rollback on the macOS PMS and I might be right as rain.

You mean this MacOS ?

This is the universal.

I’m not sure how it works other than when you open on a Mac, it should be obvious.

Apologies for radio silence, some holiday named Easter got in the way of my Plexing.

THANK YOU for the previous build link, rolling back for both the Syno and Mac seems to have fixed the issue with both immediately :- )

Wonder what happened with the newest build? Two decades of technical debt must be one hell of a thing.
