Dspmixfx ur-c remote bridge

DspMixFx UR-C remote bridge app not connecting to iPad Pro with WiFi on Windows 10. Tried every trick in the book.
Nothing works. The app does not see the my UR44c.
I have the latest firmware, the latest driver, the latest Tools.
Windows 10 Pro 64 bit
iPad Pro 12.9 latest iOS.

maybe the Windows Firewall is blocking the connection?
