Virtual Camera: cannot see viewport on Iphone

Hello everybody.
I see people with similar problems but still cannot find the solution.
I am testing the VirtualCamera plugin with an Iphone and UE4.26, and following the documentation (Virtual Camera Actor Quick Start | Unreal Engine Documentation).
With Livelink, I see the mobile in the list and I get it to track the camera, which moves within UE, but I can’t get the scene to be seen on the iPhone, the Unreal Remote 2 app always stays on “connecting”, so I can’t use it.
Anyone know what can I do? Thank you!
