Is there is a firewall, router, or security software setting blocking communication between client and server?

Support

In order for a client application to communicate with a dongle server via TCP/IP, verify that no firewalls or security software on client or server or routers settings is blocking communications.

All firewalls, security software, and routers must be set up to allow klserver.exe to communicate via TCP/IP, and must allow communications via TCP/IP port 4242. In addition, if you are not using a TCPIPSVR.DAT file to point the client to a specific server, all firewalls, security software, and routers must be set up to allow UDP communications between client and server.
