THE SOLUTION IS SIMPLE!!!
In Maya, if your bone hierarchy is inside a “group” or a “reference” that is causing the rotation problem. I uploaded two images where you can see my particular case using “HumanIk” It creates the “root hip” bone inside this reference, and for some reason, when you activate “LiveLink” the rotation of that “reference” in Maya, it’s Y-up, all you have to do is rotate it. I’m sure it’s the same for the above example.
Hope this helps in some way.
