Sublarr v1.17.4

Fixed

• Live updates work when Sublarr is not opened via localhost — Socket.IO
  only accepted the origins in SUBLARR_CORS_ORIGINS, which defaulted to
  localhost. Opened through a LAN IP or a domain, the page loaded but every
  live connection was refused, so progress, toasts and queue updates never
  arrived and no error showed. Sublarr now always accepts its own origin
  (matched against the Host header); SUBLARR_CORS_ORIGINS defaults to
  empty and only adds other origins. X-Forwarded-* headers are not
  trusted, so a reverse proxy has to pass the original Host on (Traefik
  and Caddy do by default; nginx: proxy_set_header Host $http_host;).
