Unable to access devices via Test Project Agent

I have setup TestProject agent in my machine and my teammate is trying to access it from his machine.
We both have TestProject Agent installed in our machine and on our corporate VPN.

But, we cannot access the device connected to each others machine. Getting error as “display device screen failed” upon trying to connect.

Does the VPN causes any issues? Any solution would help.
