Hi all, I’m trying to make connection between my laptop and ur5e and to use URcap for external control. I followed instruction from github to install Universal Robot Ros Driver, and also installed URcap for external control. My laptop and ur controller are connected over ethernet cable and laptop ip set to static on 192.168.0.100 and on teach pendant I setted the robot’s ip to static 192.168.0.50, subnet masks on both are 255.255.255.0. Under installation on teach pendant \> urcaps\> external control ip is 192.168.0.100 port 50002. Also on TP profinet is dissabled and also ethernet/ip dissabled. Remote control on TP set to enabled. When i ping robot ip from laptop I get response. WHen I ssh to robots controller and ping laptop I also get response. PROBLEM is when i start driver on ros side and try to run URcap external control program from TP i get error "The connection to the remote PC at 192.168.0.100:50002 could not be established. Reason: No route to host (host unreachable). I’m using laptop with only ubuntu installed 22.04 Ros is noetic. I also read here on forum everything I could find about that error and tryed every solution provided and also googled and tryed all that I can find and nothing seems to help, but maybe I was missing something. Can somebody help, please. ---

Can’t accept new action goals. Controller is not running how to solve this
