SOLVED: Roku app not showing all thumbnails

[RedBell4399]

SOLUTION at bottom of post

Since I moved my Jellyfin server into a docker container, the Roku app does not show all thumbnails. Majority are broken.

Docker image: jellyfin/jellyfin
10.8.13
https://hub.docker.com/r/jellyfin/jellyfin


However, on other devices, such as PC and phone, all thumbnails show correctly!

I have:

* reinstalled Roku app
* Updated Roku app to latest
* Restarted docker container


Tried to find a solution:

* https://www.reddit.com/r/jellyfin/commen..._jellyfin/
* https://forum.jellyfin.org/t-solved-prob...thumbnails
* https://forum.jellyfin.org/t-movie-posters-not-loading

I have been searching around for a while now and cannot find solution. When Jellyfin was on baremetal it worked correctly (that is through apt package).

As I write this, I checked the log in more detail and noticed:

Code:

System.UnauthorizedAccessException: Access to the path '/cache/images/resized-images/f' is denied.

From the host machine, I allowed access to cache folder:

Code:

sudo chmod 777 -R /path/cache/

  Changing permissions worked. I can now see all the thumbnails.

I will still post this for anyone coming across this post.
