Client constantly tries to conenct to port 21114/tcp

[thenktor]

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:

1. install open source server
2. conenct client
3. 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.

Just found at the client bug tracker: rustdesk/rustdesk#13054

"NO" and wontfix without any further explanation for this strange behaviour? So I say: Sorry, but WHY?
