Server Version#: 1.16.2.1297
I’ve noticed an error that started occurring in the Beta Plex Media Server 1.16.2.1297, related to music library scanning.
I run PMS inside Docker on Unraid using this container: https://github.com/linuxserver/docker-plex
Since running this version I’m seeing errors in my Unraid server’s system log :
Jul 14 09:56:42 Tower root: error: /gcsp/2.0: missing csrf_token
I see exactly 72 of these repeated in <1 sec.
And at the exact same time in the PMS log:
Gracenote: Exception at line 1036, error 276889603 (Item not found.)
I see exactly 36 of these repeated in <0.2 sec.
I can make the errors occur (in both logs) by running a manual scan of the Music library in PMS ("…" > Scan Library Files). They also occur when a periodic scan of my library runs (daily as per my schedule).
From a cursory online search it seems “gcsp” is related to the Gracenote SDK/API.
So while they’re errors in my system’s log, it certainly seems they’re being caused by Plex.
The type of error in the Unraid system log suggests that PMS is trying to access something on the ports the Unraid admin web interfaces runs (80/443), as this error is generated when trying to access it without an appropriate token.
i.e it’s trying to access http://<server-ip>/gcsp/2.0 which is the Unraid web interface. But my PMS runs on port 32400, so it should likely be trying on http://<server-ip>:32400/gcsp/2.0
There is a thread on the Unraid forum where a number of people are seeing the same issue: https://forums.unraid.net/topic/81612-missing-csrf_token/
Can this please be investigated.
Thanks!
