Error processing request URL GET /Items//playbacki

[PyL96]

Hello,

My Jellyfin.log keep getting spammed with the same error and I wonder why. I think it can be the cause of some of the issue encountered by my users.

My setup is:
Jellyfin 10.8.13
Installed via debian apt repo
Debian 12 x64 running in a Proxmox LXC

The logs that keep getting spammed, 1762 times in 2 hours (The item ID are not the same every time):

Code:

Jellyfin is behind Nginx on the same VLAN:

Code:

    }
   
    # location block for /web - This is purely for aesthetics so /web/#!/ works instead of having to go to /web/index.html/#!/
    location = /web/ {
        # Proxy main Jellyfin traffic
        proxy_pass https://$jelly/web/index.html;
        proxy_set_header Host $host;

Do you have any ideas ?

In the Jellyfin Nginx doc there is this setting you don't have.  Maybe this is it?

Code:

    ## The default `client_max_body_size` is 1M, this might not be enough for some posters, etc.
    client_max_body_size 20M;

You also don't have this block.  Not sure how important it is.

Code:

    location = / {
        return 302 http://$host/web/;
        #return 302 https://$host/web/;
    }

[PyL96]

client_max_body_size is already set at 512M in http context of my nginx.conf.

I will add the second block and see if that help.

[PyL96]

Doesn't seem to work.

Can you share your full log?

[PyL96]

Here you go https://www.transfernow.net/dl/20231208Xjw1MvFS
I've merged all the jellyfin.log of today.

[TheDreadPirate]

With that 302 block I had you add, swap out which line is commented out. Comment out http and uncomment https.

No change
