locked WSJT-x, JTAlert 2.50.1

Jon Baker

These two programs suddenly stopped working with each other
WSJT-X does not  populate JTAlert as it did in the last 24 hours
I am not aware of any changes to the system  i.e. updates to Windows 10 etc.
Checked the UDP setup as per the help file but they are still not talking
any ideas?
