The two most common causes of JTAlert to not receive UDP traffic from WSJTX and thus producing the error shown is
  1. WSJTX is set to run with elevated privileges. That is either the shortcut used to start the program or the executable itself (check both) is set to "Run as Administrator". There is never any legitimate reason to run WSJTX elevated.

  2. Some other WSJTX interacting application has taken exclusive control of the UDP Server port (2237 in your case)t. Try starting WSJTX and JTAlert only.

I strongly advise that you abandon the use of the port 2237 UDP server settings and utilize a multicast IP address, like on port 2237. Other WSJTX interaction applications like DX Aggregator and Grid Tracker will need to be set to use that multicast IP/Port. There is no setting needed for JTAlert as it will automatically adjust to the new multicast address.

Using multicast will allow multiple applications that interact directly with WSJTX/JTDX to run concurrently, provided they support multicast without adversely affecting the other applications, something that is not possible if using the unicast address..
