Description
Describe the bug
The clients sonstantly try to connect to port 21114/tcp on the server. The server is the open source version and does not respond on this port.
Furthermore this port is closed (dropping packets) in the server firewall because it is not used. This leads to a lot of tcp retransmissions.
Describe the environment
- Install environment: package
- If package, we need the distribution and release: FreeBSD 14.3
- server 1.1.14, client 1.4.3
How to Reproduce the bug
Steps to reproduce the behavior:
- install open source server
- conenct client
- see endless connection attempts
Expected behavior
On an open source server the client should not try to connect to port 21114 or the server should respond with a "here is nothing" message that stops connection attempts from the client.

Research direction
Reproduce the behavior with an open-source server on FreeBSD 14.3, using server 1.1.14 and client 1.4.3, and observe the repeated connections to port 21114/tcp. Trace the client/server connection handling to determine why attempts continue; done means the client no longer repeatedly connects to that unused port or receives a response that stops the attempts.
