When clicking on content I get a "Something Went Wrong, Retry" message repeatedly, but then it works

Plex Media Server
,
1

Server Version#: 1.28.0.5998
Player Version#: Android-TV, Shield, ATV

I have a constant issue that when I go to open a piece of media the following things happen:

  1. Click the Movie Poster
  2. The app goes partially into the Movie description - the background art changes and the movie name pops up, but no play buttons, actors, more films etc. pop up
  3. I get a “something went wrong, retry” error
  4. I click retry 3 or 4 times
  5. Finally, everything works fine.

It’s incredibly annoying and is generally consistent, but occasionally it’s doesn’t happen and I don’t know why it works. I never run into these issues on the web player.

Things I’ve tried:

  • I was running in Docker Bridged Mode on a remote server. I switched to a Docker Host Mode setup as to not run into NAT issues with Docker itself.
  • Not requiring Secure Connections
  • Disabling ipv6
  • Disabling Relay
  • Setting Preferred Network
  • Cleaning / Repairing Database

I cannot figure this out for the life of me.

In the log files I see that I’m getting issues where it looks like it’s timing out trying to talk back and forth.

Here are the logs from my player: 29/plex/stable/package/a3d5bb79a74c0212659f1789f7867615017c99be/include -DLIBXML - Pastebin.com

and server logs are attached below.

Thank you for the logs:

  1. /transcode ? Is this a container? Error is “Not writable”.

There are other errors but they are likely the result of the primary DNS failure.

Hi There -

I took Docker out of the equation and am still running into the same issues on bare-metal. From what I can tell - DNS is working fine. Can you look over these logs and let me know if you see anything further? Also - where are you seeing the errors - there are so many log files to look through that I don’t know where to start.

Thanks again for the assistance.

I’ve been doing some further testing.

The issue appears to be a delay in propagating the actor, trailer, related metadata for android TV apps, IOS Apps and ATV Apps. I’ll select a movie and the page will start to load, but not provide any of the additional info for up to 30 seconds. Once it loads, I can then select any other movie and it will load instantly. This keeps working for that browsing session, but after an amount of time, maybe 10 minutes, it goes back to one very slow load until it works again.

On ios - it just sits still and hangs. On Android TV it gives a “something went wrong, retry” error. Retrying multiple times eventually allows the app to punch through.

I never experience these issues in the web app on my browser or the PC plex player app, on the same network in the same house. I do experience the issue in other locations, so I don’t think it’s my home network.

I’ve tried deleting the cached plugins - to no avail.

Here is a video of the problem happening on mobile.

And on Android TV

Thanks @ChuckPa !

6

Any chance you could take a look at the updated logs @ChuckPa ? I can’t figure out what the issue is on my own.

7

That is pretty wonky.

Using these logs Plex Media Server Logs_2022-07-25_09-39-35.zip (3.9 MB) from 3 days ago,

That Chrome device is SPEWING requests like it’s nobody’s business and beating hard it.

If you look, you’ll see several requests separated by single-digit milliseconds.
I’ve never seen a PMS client misbehave like that.

What is this Chrome device ChromCast ? Web?

8

It would just be a web browser. I don’t have a chromecast.

9

Web browser is the only player that doesn’t grind to a halt upon browsing for new movies tho

10

That TV looks a lot like the app / WiFi is not working right in the TV.

When’s the last you updated it / reloaded the app?

Are both WiFi ? If so, 2.4 Ghz or 5 Ghz?

11

All are up to date on 5 GHz. The TV has an Nvidia Shield connected and it has the same issues as the native TV app. I see the same problem at different homes on different networks. I have tried rebooting many times. I also show the same issues on the iOS client and apple tv client.

12

You certainly have enough CPU power for this. (I have a 2690v4)

How’s the server connected and is it running native on the host?

13

The Server is a VPS XL on Contabo located in the US. It’s been running without issues for years now. This is a new issue that popped up.

It’s just strange to me that I don’t see these issues through the web app at all - instant loads, but on pretty much every other client I get that huge initial lag (and on Android TV - I get timeouts until it finally loads).

14

And yes - I moved it to running Natively from running in docker to see if it would help with my issues - but I still see them.

Could it potentially be something to do with the database? I’ve checked for errors using PlexSQL and all looks fine. Also removed all caches.

15

If you were having database issues, the first indication would be “SLOW QUERY”.
Those fire if any query takes more than 250 ms to complete.

How many vCPUs of that 10-core (20 thread) are you getting?
They advertise 10 core but how many other customers are you sharing with ???

To keep you and them separate, you must be abstracted from the hardware so either it’s a Linux Container or a VM (maybe ESXi)

16

I am supposed to get 10. I show 10 in htop. Watching htop while clicking something in ios show very little activity, but very slow response in the plex app.

17

That really does wreak of network performance given it’s remote.

What that actually is is going to require a lot of digging.
Process of elimination –

MTR test (hop test)

Start with mtr ip.addr.of.server

IPERF3 test (sustained throughput)

  1. install iperf3 on the VPS
  2. start the server iperf3 -s
  3. Install the same app iperf3 on your workstation
  4. run a test
    – iperf3 -c ip.addr.of.server -t 15
    – iperf3 -c ip.addr.of.server -t 15 -R

( -t is how long to run. -t 60 runs for 60 seconds)

Please report all findings.

That’s showing us 30 Mbps usable (combined).
Is this speed rate expected?

I did some tests using parallel connections and got much faster speeds - see below.
