Caddy reverse proxy redirect loop

[proess880]

I want to deply metub behind Caddy (docker) as a reverse proxy. However i am unable to get it redirected properly.

docker-compose.yml

services:
  metube:
    image: ghcr.io/alexta69/metube
    container_name: metube
    restart: unless-stopped
    networks:
      - proxy
    volumes:
      - /media/share/Downloads:/downloads
      - ./data:/app/data
    environment:
      DOWNLOAD_DIR: /downloads
      STATE_DIR: /app/data/state
      TEMP_DIR: /app/data/temp
      URL_PREFIX: /metube

networks:
  proxy:
    external: true

Caddyfile

https://services.mydomain.com {
    handle_path /metube/* {
        uri strip_prefix /metube  -> Also tried removing this line since **handle_path** does the same
        reverse_proxy http://metube:8081
    }
}

but i get an infinite redirect loop

And the logs of the container there are errors

URL_PREFIX: /metube handle_path /metube/* { ~uri strip_prefix /metube~

or

URL_PREFIX: / handle_path /metube/* { uri strip_prefix /metube

[proess880]

it only worked after setting URL_PREFIX: / and accessing with https://services.mydomain.com/metube/ (Notice the trailing slash is important) Which kinda makes URL_PREFIX obsolete

Caddyfile

https://services.mydomain.com {
    handle_path /metube/* {
        reverse_proxy http://metube:8081
    }
}
