Failed Playback Roku and Android

[kevinsparenberg]

I’m having problems with playback after my most recent update to Plex Media Server 1.41.7.9823-59f304c16, but only on Roku and Android devices - Plex Web works fine from any server.

Symptoms (Android):

• Find a show I want to watch.
• Browse to the show, season, episode.
• Click play (or resume).
• Screen “rotates” for player, but immediately throws an error.
  
  

Similar experience with Roku except the “progress” circle always goes to 33%, then restarts, hits 33%, tries it again, then fails with a similar “Retry” message.

Servers Details:

1. Primary: Ubuntu Server (headless) running 24.04.2 LTS (Noble Numbat)
2. Secondary: Windows 11
3. Failover: Synology NAS DS1520+ (DSM 7.2.2-72806 Update 3)

Media Details:
Stored on a NAS accessible via CIFS (was using originally) [Library Name: TV Shows]
Also accessible via NFS (setup for troubleshooting) [Library Name: TV Shows (Test)]

I’ve attempted but didn’t fix:

• Adding an NFS Share instead of a CIFS share in case it was a permission issue.
• Removing IPv6 support.
• Chaning Interface to “Any” from specified ones.
• Toggling Allow Relay
• Toggling Strict TLS configuration.
• Unsetting my LAN Networks (set as 192.168.0.0/16) [P.S. does anyone know the 'equivalent of this for IPv6?]
• Toggling Treat WAN IP as LAN

Frankly, I’m at a loss at the moment and am about to go on vacation.

I’m including a set of one server’s logs (anonymized as best I can) if that helps.

I was trying to watch a show last night on my phone and the damned thing kept throwing this error or a similar one every three to four minutes. Just too annoying. I’m going to roll back to the “Old, (non-)Busted Experience” for now, because this BS is getting on my last nerve.

In rudimentary testing, it feels like Remote Access is broken and that’s causing waves into other areas of the software.

I was on holiday last week and was able to watch anything I wanted remotely without incident - that was great. Then I wanted to pick up where I left off at home and none of the servers would stream “locally” - each threw the same error message as indicated above.

Is there something I’m missing here?

Additional “troubleshooting”: I even setup a docker image and pointed it to the same libraries to test. Once that docker image was configured for “remote connection” the local streams would fail. It’s very odd behavior to say the least.
