This type of error is typically caused when using a unicast setup in WSJT-X ( and other applications interacting with WSJT-X taking exclusive control of port 2237.

Setup WSJT-X to use Multicast UDP, this will allow multiple applications to operate concurrently working with WSJT-X, provided they have been set to use multicast UDP. JTAlert setup for multicast is automatic except for enabling a single menu entry. Other applications require some work to use multicast, refer to the appropriate support documents for those applications.

See the JTAlert Help file, "WSJT-X UDP Setup" topic on how to setup WSJT-X correctly to use multicast UDP.
