You should probably check that the DriverStation and roboRIO have the same team number. Can you reach the roboRIO Web Dashboad?

I mean stupid question here, but have you checked the firewall settings and either A. Disabled all of them (public, private and domain) or B. Allowed the specific apps needed for FRC comms Wpilib docs for this in windows

Why do you believe your code might be affecting the mDNS service?
