Current Behavior

I was running Jellyfin behind Traefik v3 which worked perfectly, however after a recent version update of the Jellyfin image, the web client now hangs at the splash screen after throwing 404s for its javascript dependencies:

GET /web/node_modules.%40mui.icons-material.bundle.js?4eb8ea179f4fc2baed3a net::ERR_ABORTED 404 (Not Found)
web/:1

GET /web/node_modules.react-router-dom.bundle.js?4eb8ea179f4fc2baed3a net::ERR_ABORTED 404 (Not Found)

Expected Behavior

The web interface should load with no 404s

Steps To Reproduce

1. Start jellyfin with docker-compose
2. Navigate to jellyfin
3. Observe page is stuck on jellyfin logo and JS dependencies 404
