Once again you encounter the pitfalls of numerical computation. Solve (as well as Reduce) handles this set of equations and constraints easily, and with no error.
You used N[Solve[...]]
while there are very high powers of the arguments (try Reduce without N, and you will see)
So, just replace
N[Solve[...]]
with
N[Solve[...],100] for accuracy of 100 digits and you will be surprised to see that

So the solver keeps the constraints, but numerical computations need to be handled carefully
