The reverse proxy MUST be configured to support WebSockets, as it is needed for clients running Tailscale v1.30+. The reverse proxy MUST be configured to support WebSockets to communicate with Tailscale clients.
WebSockets support is required when using the headscale embedded DERP server. In this case, you will also need to expose the UDP port used for STUN (by default, udp/3478).
