Hello everyone,

I want to connect my ur3e with my Pc via an ethernet connection an use the rtde function. I’m going to use a python script I found here: [GitHub - UniversalRobots/RTDE\_Python\_Client\_Library: RTDE client library and examples](https://github.com/UniversalRobots/RTDE_Python_Client_Library.git)

I already managed to connect my ur3e and I’m able to successfully ping in cmd. I also added the port 30004 in the firewall settings, but for whatever reason my Pc cannot identify the network connection. I’d be happy for any kind of help.
