Thumbnails and video streams appear corrupt?

[gts250gamer]

Hey all!

I have been using Jellyfin for a few years now, and I have migrated the library between servers a few times in this span. I am encountering a bizarre issue with the current server hardware and configuration, in which thumbnails in certain resolutions appear to load incorrectly in the Jellyfin Media Player software or web UI.

This is how the thumbnails are rendering on the client side:



The issue persists across devices and doesn't appear to affect media playback on the server when I remote in to the host.

Likewise, there have been some issues with playback as well, with artifacts appearing over the video while it is playing, even during direct stream when no transcoding takes place.

I am really at a loss here for what to try, as it seems as though the media is not corrupt on the server side (videos play just fine locally on the server as well, albeit slightly choppy as it is a remote connection). Any advice would be much appreciated!

Server hardware:
- Intel Core i3-13100T processor (4c/8t)
- 64GB DDR4 memory @ 2400MT
- 512GB NVMe boot SSD, 2 x 4TB WD spinning disks for Jellyfin media library, mirrored nightly
- Intel Arc A310 Eco GPU

Can you share your full jellyfin log via privatebin.net?

And can you run this command and share the output?

Code:

curl -vvv https://image.tmdb.org/t/p/original/uqIVJR1fmkiwpcIsIcV0vxiyY4z.jpg -o /tmp/futurama.jpg

If you're on Windows change the file path at the end to a valid windows path. But everything else should work on Linux or Windows.

Sorry for the late reply, I got busy with uni work... I am running Windows Server 2025, went ahead and ran the command and it looks like everything went OK... Here is the output from the command. Appears to have downloaded the jpg successfully to the desktop, I can open it and view it just fine.

The only thing I see is this.

Code:

16:42:38.209825 [0-0] == Info: [WRITE] cw-out is notpaused
16:42:38.212238 [0-0] == Info: schannel: failed to decrypt data, need more data

Your version of curl outputs more low level messages than what I can get in curl on Linux so I can't say if this is normal.  But to me it looks like there was some network blip that caused a re-transmit.

Since you said it also affects video streams, to me this sounds like there is some issue with your server's network connectivity.  I can't say whether this is an issue with the NIC, the cable, router.  But I am leaning towards some network related issue.

Thank you for your help! I am going to try replacing the network cables this weekend, to see if that improves anything. I have a dedicated NIC I might install too, just to see if that solves the issue. Hadn't even occurred to me that could be the culprit, I was panicking that perhaps my drives were getting long in the tooth or something... I appreciate the help, DreadPirate!
