Private access to Subtitles
Provider search/download traffic is outbound. It does not require opening the Subtitles web port to the internet.
Use the local browser, a private SSH forward, or the Server’s configured private-management connection for remote administration. Finish Owner setup and strong authentication before enabling other devices. Do not expose the administration listener through a router forward.
Public media viewing belongs to Kinosail Player’s separate restricted HTTPS boundary. Subtitles does not need that workflow to write sidecars. See device access and security.
