Lots of these errors whenever I enable transcoding on my K600. I had it working on an older version of Ubuntu, but lost the VM guest and had to rebuild. I see a transcode start on nvidi-smi, then cease almost instanly. The media will play for ~10 seconds, then die. I did find an old thread here "404 GET /video/:/transcode/universal" occurring in Ubuntu 18 after upgrade and tried removing easy audio encoder, but that didn’t help at all. I’ve changed the transcode directory and made sure it’s owned by plex:plex with 775 permissions. My old db backup and metadata folders went in without a hitch. It’s only media transcoded with GPU that’s having this issue. CPU transcoded is fine. I’ve tried it without the GPU patch too and haven’t had any luck.

Need the full logs ZIP to see what happend. Sorry but it’s impossible to diagnose from a snippet.

Reference please? What’s a K600?

mautobu · May 22, 2020, 11:05pm

Sure thing. Nvidia K600 is an older workstation graphics card. Plex Media Server Logs_2020-05-22_23-04-16.zip (2.5 MB)

ChuckPa · May 22, 2020, 11:22pm

Where is the transcoder temp pointing to?
Is it local or across the network (LAN) ?

From the logs, I see the transcoder writing but don’t see anything reading successfully.

Also, please look at:

Transcoder temp is at /var/lib/trandscode locally on the plex server. SSL issue I would guess is from navigating to the plex web client directly on the server. Like, a local ip address instead of app.plex.tv. I’ve tried the clients on plex.tv, and navigating to the local server ip address.

Just tried the windows client (1.11.0.1215) again and receives error 4294967283 (unknown error). Logs popped up Unable to find client profile for device; platform=windows, platformVersion=10.0.18363, device=, model=standalone. I can re-upload logs if that would help.

mautobu · May 22, 2020, 11:35pm

I thought I had updated my windows plex client, but apparently not. Doing that now…

mautobu · May 23, 2020, 12:13am

Looking into the SSL stuff. Is it possible to force a new certificate? I’ve unclaimed and re-claimed the server, not sure if that should do the trick or not.

ChuckPa · May 23, 2020, 12:14am

Do you have your own certificate somewhere in the chain?

mautobu · May 23, 2020, 12:15am

I do not. Just 32400 open to the web.

ChuckPa · May 23, 2020, 12:16am

best you can do is give it a restart and let it work itself out.
If there were a certificate file, I’d have you delete it but the cert is in the DB.

mautobu · May 23, 2020, 12:24am

I’ve given it several restarts. Should the cert give an error if it were good and I were to navigate to https://myplexserver:32400/web?

There are a couple of keys that have warnings on them, but I’m sure it’s normal.

Key Usage:
Digital Signature, Key Encipherment (a0)

Basic Constraints:
Subject Type=End Entity
Path Length Constraint=None

Since I did restore this database from an older plex server and removed the old plex server from my account, could that be affecting it? I’m still baffled as to why it’s only affecting media transcoded by a GPU.

ChuckPa · May 23, 2020, 1:19am

is myplexserver a FQDN or just an IP ?

mautobu · May 23, 2020, 3:27pm

Local IP

ChuckPa · May 23, 2020, 4:05pm

Unfortunately, I have no clue as to why.
There is a cert / MITM / something in the socket layer

This is native host, a snap, VM, or container?

mautobu · May 23, 2020, 5:12pm

It’s a VM. Hosted by KVM.

ChuckPa · May 23, 2020, 6:15pm

Is there a cert on the VM host ?

Remember, a VM’s traffic must pass through the host.

mautobu · May 24, 2020, 4:24am

No there’s not. Network is bridged is bridged anyway. There’s no host NAT.

Going to try again on an install of 18.04 and see if the older kernel does anything to help.

mautobu · May 24, 2020, 6:29am

Welp, seems to be working just fine on 18.04. Might have been an issue with the nvidia driver or the patch. I had written out my entire install procedure in case I needed to run through it again. I guess that paid off.
