External Control URCap program throws connection error after running program

[zafarkamil]

Hi,

I am running into an issue when executing a program with the External Control URCap program node inserted. I have attached a screenshot of the error that pops up. Running Polyscope 5.22.2. The PC is able to ping the robot and I am able to launch RViz successfully using instructions from the UR docs page in this link.

"The connection to the remote PC at 192.168.1.1:50002 could not be established. Reason: Connection refused"

"Connection refused" usually points to a firewall being active on the remote PC blocking external access to that particular port. Please check for any active firewalls on your ROS machine. You should be able to configure your firewall to allow connections to port 50002 (allow connections to 50001, 50003 and 50004, as well, as they will be needed by the script code running on the robot).
