URCAPS External Control: Connection refused

edit

Good evening, I am trying to follow this tutorial https://github.com/UniversalRobots/Un...

Reproducing every step works except step 5 under "Connect to External Control via URCap".

What we have tried:

• Using default port
• Using port that we thought it would listen to

Errors we get when configuring on universal robot pad:

• "The connection to the remote pc at 192.16.1.100:50002 could not be established. Reason: Connection refused"

I doublechecked the IP-address of my ROS PC in externalcontrol under the installation tab on the tablet and it is correct. We can ping the robot (192.168.1.10) which is working. Robot specifications:

UR10
URSoftware 3.15
External Control URcap version 1.0.5

IP addr show output:
