Disable open user registration after setting up your account. This can be done via the /admin web panel, if enabled, or by adjusting the config.json file. Alternatively via environment variables. See documentation here.
⚠️ Note: The WebSockets service for live sync has been integrated in the main HTTP server, which means simpler proxy setups that don't require a separate rule to redirect WS traffic to port 3012. Please check the updated examples in the wiki. It's recommended to migrate to this new setup as using the old server on port 3012 is deprecated, won't receive new features and will be removed in a future release.
