Troubleshooting

Connection Issues

If you are trying to connect to the Debug Server from a Workers application running in LabVIEW, and you don't see the Workers application appear in the Debug Server, then the Windows firewall has probably blocked the connection of from occurring.

By default a Debug Client will try to connect to a Debug Server over the localhost (which corresponds to IP address 127.0.0.1) on port 6891.

For both LabVIEW and the Debug Server, both need to be able to communicate over either the Windows Private network or the Windows Public network. This is why when you first load the Debug Server, you need to select which network you want the Debug Server to be allowed to communicate over, and it is recommended that you select both networks to assure connection between Workers applications running both locally on the same machine or remotely over a network.

Cannot reconnect in Client Mode

Applies to Debug Server running in Client mode and Debug Client running in Server mode.

If a Workers application is terminated abruptly on a real-time target such as a cRIO, when you try to run the application a second time, you might not be able to immediately connect to it again from the Debug Server. However, after waiting a duration of approximately 60 seconds, it should be possible to establish a connection again.

To avoid this, always shutdown your Workers application cleanly, either from within the application itself or by use of the Start Exiting option in the Task Manager's right-click menu.
