Class project- action server error message: Inbound TCP/IP connection failed

Course Support ROS Basics In 5 Days (Python)

When I test my action server things seem to be fine. However when the server has completed I get an error message “[WARN] [1608507304.704117, 2076.382000]: Inbound TCP/IP connection failed: connection from sender terminated before handshake header received. 0 bytes were received. Please check sender for additional details.”

I’ve tested twice (once to let time run out, and once driving the robot out of the maze to see if the action ends appropriately). Both times my client got the result message just fine. But both times I got that error message (with different timestamps of course). Am I doing something wrong with the server or client to generate this error message? It hadn’t happened with the previous exercises.

Thanks,

This is communication warning message that is quite common, but it doesn’t necessarily mean there is anything wrong with the server or client, it appears even when you’re not using them.

Thanks - so I can safely ignore it?
