Describe the bug
When rustDesk connects to a remote host, rustDesk displays "The connection was closed by the other host", and a loop appears.
hbbr in rustDesk-server always loops error logs as follows:

docker container: hbbr

Describe the environment

• Install environment: docker, centos7
• docker-compose install rustDesk-Server .
  

Start with the relay log entries in src/relay_server.rs around lines 425-441 and reproduce the connection through the Docker Compose deployment on CentOS 7. Compare the client’s connection-closed loop with the relay lifecycle shown in the logs; done means the relay no longer closes the connection unexpectedly and the remote session connects successfully.
