connect robodk to AR2

Hi everyone, I'm a student and I try to make a complete project where I need to use the robot AR2.

To generate my code and simulate the robot I use RoboDK but now it's time to send the program to my robot and I can't.

If someone has already done this before, can you contact me to help me please ?

I can't connect my robot to the software, it says :

I'm a beginner in this world so I know I made something wrong but I don't know what ?

Thank you for your help !
