StarSat Hyper 2000 HD GMScreen not working!

[frozenflame99]

I have StarSat Hyper 2000 HD with latest firmware. Also updated latest G-MScreen from play-store but it is not connecting.
Error is setup top box not reachable.
Both mobile and Hyper are connected to same WiFi.
It works few months back but not it is not even connecting.
What to do?
i don't want to downgrade as Cline is working perfectly fine on latest firmware.
Any other solution?
