Key Mismatch since version 1.1.11

[loxK]

Describe the bug
I run multiple self-hosted RustDesk servers using docker and the sample docker-compose.yaml. On version 1.1.9 they work well. If I upgrade to more recent versions I get key mismatch error. (1.1.11 to 1.1.14, 1.1.10 being buggy and not running at all)

Describe the environment

• docker compose on Ubuntu 24.04 (both Docker as Snap or docker-ce official package)

Sample docker compose file :

networks:
  rustdesk-net:
    external: false

services:
  hbbs:
    container_name: hbbs
    ports:
      - 21115:21115
      - 21116:21116
      - 21116:21116/udp
      - 21118:21118
    image: rustdesk/rustdesk-server:1.1.9
    command: hbbs -r [redacted domain]:21117
    volumes:
      - /opt/rustdesk:/root
    networks:
      - rustdesk-net
    depends_on:
      - hbbr
    restart: unless-stopped

  hbbr:
    container_name: hbbr
    ports:
      - 21117:21117
      - 21119:21119
    image: rustdesk/rustdesk-server:1.1.9
    command: hbbr
    volumes:
      - /opt/rustdesk:/root
    networks:
      - rustdesk-net
    restart: unless-stopped

How to Reproduce the bug

1. Install 1.1.9, setup the clients with the public key
2. Test and notice it working
3. Upgrade to any version higher than 1.1.9
4. notice the key mismatch error

Expected behavior
There should be no error.

Additional context
I have searched any migration information in changelog, but found nothing. There is the mention of the "-k" option, but it is undocumented.

Nobody else has the issue ? I have it on three different servers ...

I tried with adding the key with -k in both hbbr and hbbs commands. The key is also reported correctly in /opt/rustdesk/id_ed25519.pub and in the output of docker containers.

As soon as I switch back to 1.1.9, everything works well.

Same here, but with .deb installation.

I guess the only solution is to revert back to older versions, which seems unsafe and overall a bad solution for this type of software.

And i assume most people never update their server instances, so there aren't many complaints about this so far.

Same here, Even if I specify the pub content with -k, Key Mismatch still occurs.

I have been banging my head against a wall trying to get this to work for the last few days using nssm on a Hyper-V VM. Connections are successful from clients to server but no matter what I had tried, I kept getting the key mismatch error. Has there been any word of a fix?

Same here, when can we expect the fix? It's a matter of security!
