Bug Description

Hello,
I have set up a self-hosted RustDesk server (hbbs/hbbr) on Ubuntu VPS.
Ports 21114–21119 are open and verified (UFW and ss confirm services are listening).

On MacOS, iPhone, android Tab the connection works fine through my server:

On Windows 10/11 client, however, we always get “Deadline elapsed” when trying to connect.

We have already:

Installed RustDesk client with RustDesk Service on Windows.
Verified Get-Service -Name rustdesk → status is Running.
Disabled Windows Firewall completely (also tested with rules allowing RustDesk).
Confirmed server key and relay/IP are correct (if the key is wrong, we get “Key mismatch”, but with correct key only “Deadline elapsed”).Tested with WebSocket on/off — same issue.

So the server seems fine (since Macs/iPhone/android tab work). The issue appears to be specific to Windows client.

Key question:

What additional configuration is required for Windows clients to connect to a self-hosted RustDesk relay?Is this a known issue with the RustDesk Service on Windows, or are we missing a step?

Free version run smoothly so we upgraded, but encountered with this issue.Thanks a lot for your help!

How to Reproduce

Steps to reproduce:
1. Deploy a RustDesk self-hosted server (hbbs + hbbr) on Ubuntu 22.04 VPS.
• Open ports 21114–21119 in UFW.
• Confirm services running (ps aux | grep hbbs/hbbr) and listening (ss -tulpn | grep 21118).
2. Configure clients with:
• Relay/ID server = <server_ip>
• Key = <server_public_key>
3. Connect from MacOS or iPhone client → works correctly (connection established).
4. Connect from Windows client (x64, with RustDesk Service installed and running) → always fails with “Deadline elapsed”.
• Tested with/without WebSocket.
• Firewall disabled or with explicit allow rules.
• Wrong key shows “Key mismatch”, correct key leads to “Deadline elapsed”.

Expected Behavior

Expected behavior:
Windows client should connect to the self-hosted server the same as MacOS and iOS.

Actual behavior:
Windows client fails with Deadline elapsed, even though the same server works for Mac/iOS.
