QGroundControl on Herelink - "Error Binding UDP"

Hello everyone,

I have installed Herelink-QGroundControl v4.4.0, but I encountered the error:
“Error binding UDP, bound address is already in use.”

To resolve this, I created a Comm Link in QGroundControl using port 14551, but I am still not receiving any data from the vehicle—QGC remains disconnected.

What I have checked so far:

:white_check_mark: Herelink is successfully connected to the AirUnit.
:white_check_mark: MAVLink Router is running, forwarding data on port 14550.
:white_check_mark: QGroundControl is listening on port 14551 (netstat confirms it).
:x: Despite this, no telemetry appears in QGroundControl.

Has anyone experienced a similar issue? Any suggestions on how to ensure QGroundControl receives MAVLink data correctly?

Thanks in advance for any help!
