[denisosteo]

Describe the bug
hbbs process exits with illegal instruction - core dump. While hbbr process works fine.

Describe the environment

• Install environment: ubuntu 24.04.1 x86_64 - intel CPU - Cloud VM
• Trying to install RustDesk Server 1.1.14 amd64

How to Reproduce the bug
Steps to reproduce the behavior:

1. Ufw configured to allow port 2115:21119/tcp and 21116/udp

2. All system/packages upgrades and updates applied

3. Download RustDesk server 1.1.14 using:

    sudo wget https://github.com/rustdesk/rustdesk-server/releases/download/1.1.14/rustdesk-server-hbbr_1.1.14_amd64.deb
    sudo wget https://github.com/rustdesk/rustdesk-server/releases/download/1.1.14/rustdesk-server-hbbs_1.1.14_amd64.deb

4. Install package hbbr

    sudo apt install ./rustdesk-server-hbbr_1.1.14_amd64.deb
    sudo systemctl status rustdesk-hbbr

ALL WORK FINE

5. Install package hbbs

sudo apt install ./rustdesk-server-hbbs_1.1.14_amd64.deb
    sudo systemctl status rustdesk-hbbs

If 1.1.12 works, could you try out https://github.com/21pages/rustdesk-server/releases/tag/untagged-b143348d8880e00fcf42 and show the logs?

[denisosteo]

@21pages Version 1.1.12 works fine. If it support client versions, it's enough for now.

The provided ling returns 404.

Here is the log of hbbs with version 1.1.12

Which raises some question. Why the rendezvous-server (hbbs) needs to connect to 183.194.167.16? And what is this server? A self-hosted server is not suppose to exchange data with other systems (except his clients).

relay-servers is left empty. That is not a big problem assuming we don4t want to use RELAY. But does that means the hbbr service is useless? Or the default is same host as rendezvous-server with default port? Or shall we update service definition to pass value of relay server have environment variable?
