 The above `21115-21117` are the minimum required ports for RustDesk to work, these handle the signal and relay ports as well as NAT traversal.
 
-Additionally TCP ports `21118` and `21119` can be opened if you want to use the [RustDesk Web Client](https://rustdesk.com/docs/en/dev/build/web/).
+TCP ports `21118` and `21119` are the WebSocket ports for the [RustDesk Web Client](https://rustdesk.com/web/), but it won't works if you open them, it needs a reverse proxy to make it support HTTPS, please refer this [sample Nginx configuration](/docs/en/self-host/rustdesk-server-pro/faq/#8-add-websocket-secure-wss-support-for-the-id-server-and-relay-server-to-enable-secure-communication-for-the-web-client).
 
 For Pro users without an SSL Proxy you will need to open TCP port `21114` for the API to work alternatively using an SSL Proxy open TCP port `443`.

 #### Ports
 
-By default, `hbbs` listens on 21114 (TCP, for web console, only available in Pro version), 21115 (TCP), 21116 (TCP/UDP) and 21118 (TCP), `hbbr` listens on 21117 (TCP) and 21119 (TCP). Be sure to open these ports in the firewall. **Please note that 21116 should be enabled both for TCP and UDP.** 21115 is used for the NAT type test and online status query, 21116/UDP is used for the ID registration and heartbeat service, 21116/TCP is used for TCP hole punching and connection service, 21117 is used for the Relay services, and 21118 and 21119 are used to support web clients. *If you do not need web client (21118, 21119) support, the corresponding ports can be disabled.*
