[BUG] Bunkerweb messes with Jellyfin-Kodi playback (File ended prematurely error)

Description Connecting from Jellyfin for Kodi addon to a Jellyfin server reverse proxied through Bunkerweb creates errors during playback. Randomly (generally after 2-3 minutes into the playback), the playback fails with the error File ended prematurely in Kodi logs. (Full Kodi logs: https://paste.hostux.net/?e233fd10ea6fc475#99LpcuAJn34f6j6GU9MGSJq2m9D54DXGNYSPpqatj7ZY)

When this happens, Bunkerweb logs don't show anything in particular (except the information that the playback stopped ["POST /Sessions/Playing/Stopped HTTP/1.1" 204 0 "-" "Jellyfin-Kodi/0.7.10+py3")

I am 90% sure this comes from Bunkerweb as this happens to all Kodi clients on various machines (Windows, Odroid N2, Raspberry...) and connecting the same directly to the Jellyfin ports (without the reverse proxy) works like a charm.

After discussions with Jellyfin for Kodi addon team, they also think it comes from the reverse proxy.

Config Here is my config for Jellyfin (using autoconf):

    labels:
      - "bunkerweb.SERVER_NAME=stream.mydomain.com"
      - "bunkerweb.ALLOWED_METHODS=GET|POST|HEAD|DELETE|PUT"
