Error message when trying to connect the recorder client to the server

The problem could be that wrong IP address or port number is configured, or that the default command port 8080 is used by another service.

To check the IP address and port number, open the Recorder Configurator and the Playback & Configuration Client. Verify that the IP address and the port number are identical:

• IP address = the IP address of the Recorder Server. Use the IP address (not "localhost" or 127.0.0.1) also when Recorder Server and Client are running on the same machine.
• Port Number = The port used for communication between the Client and the Recorder Server
