Receiving data from External host?

I am trying to read data from external host computer, using TCP/IP protocol in python (Ethernet connection) over port 30002 and store that data in variable in an already running Polyscope program.I have a UR3 robot (CB 3) polyscope version 3.8.

Subnet mask on my UR3 and PC was different hence my server (PC) was not able to listen to client (UR3). Making them same enabled me to send data from external host to UR3 using the above tutorial.
