Cannot enter App through Wifi

Hi,

When I try entering the App on my iphone with the Wifi ON an error pops up that says “The internet connection appears to be offline” which actually isnt offline.
When I try entering the app on the iphone with LTE data and wifi OFF I can enter the App bu cannot setup the cameras.

How can i fic this so i can setup the cameras?

Thanks!!
Regards,
Mark
