Can you also post the the FFmpeg log after you have turned on the subutitles? Also, what client are you having issues with? Is it a specific or only one in particular? And what are your server specs.

There seems to be an issue with your GPU configuration. Please provide details about your setup. If you're using Docker, please share your Docker Compose file as well.

I dont have a dedication GPU so it would be the IGPU and here is the docker compose. 

the subtitles used to work untill one day randomly they stoped

Here is the docker compose--

services:
  jellyfin:
    container_name: jellyfin
    image: ghcr.io/jellyfin/jellyfin:latest
    user: '0:0'
    ports:
      - 8096:8096/tcp
    restart: unless-stopped
    volumes:
      - /mnt/docker/jellyfin/configConfused-faceconfig:rw
      - /mnt/docker/jellyfin/cacheConfused-facecache:rw
      - /mnt/Vol1/MediaConfused-facemedia:rw
      # rw = read & write
      # ro = read only

You need to pass you GPU you into the container. See here: https://jellyfin.org/docs/general/administration/hardware-acceleration/intel/#configure-with-linux-virtualization

Here's my compose file for example:
services:
Code:
  jellyfin:
    image: jellyfin/jellyfin:latest
    container_name: jellyfin
    user: 1000:1000
    group_add:
      - "44" #video

      - "992" #render
    network_mode: 'host'
    volumes:
      - /home/max/Dockers/Jellyfin/Config:/config
      - /home/max/Dockers/Jellyfin/Cache:/cache
      - /media/Movies:/Movies
      - /media/TV:/TV
    restart: 'unless-stopped'
    devices:
      - /dev/dri/renderD128:/dev/dri/renderD128

You'll also need to add the Intel OpenCLDocker mod for Jellyfin into the environment variables of your compose file since your using LSIO Docker image.

Code:
DOCKER_MODS=linuxserver/mods:jellyfin-opencl-intel
