This article explains how to troubleshoot issues when connecting CPRog/iRC to a robot. Go to the section that matches your connection type.

CAN

Make sure that the CAN adapter is plugged in, the wiring is correct and the robot is powered on.
Make sure the CAN adapter is recognized by your computer and that it uses the correct driver.

CPRog/iRC differentiates two types of connection issues:

This error happens if the robot is not reachable via the network:

The connection refused error happens if the robot is reachable but does not respond:

Go to the section that matches your error message.

Check that the ethernet wiring between your PC and the robot is correct and that you are using the correct ethernet ports. Check that the robot is powered on.
Make sure that the IP address of your PC's ethernet port is correct. If the IP of the robot is 192.168.3.11 the IP of your PC should be set to a similar IP that does not end with 11.
Use ping to check if the robot is reachable by it's IP address.

If you can ping your robot but not connect to it with CPRog/iRC go to the next section.

This might mean an issue with the control software of the robot (TinyCtrl).

Turn the robot off and on again and try to connect.
Update TinyCtrl, if it isn't the most recent version already or if you're not sure.
If you still can't connect to the robot send the Log Files of CPRog/iRC and TinyCtrl to our support.
