Problem with Camera Matching and fspy

Hello all.

Im using the fspy software and addon with Blender 2.83. Im trying to recreate a 3D scene from 2 photos. My problem is that i cant get them match properly. I dont know where im wrong. Im putting here a wetransfer link with recorded video. It shows my workflow in using fspy. Is something wrong im making ? As you can see in the video from the link the cube doesnt want to match with the two cameras.
