I try to use NSolve to obtain the numerical solution to a system of equations, but the out of Mathematica is same as my put-in.

NSolve[{-1.2 x + 0.0637 ArcTan[2.1991 y] +
0.06367 ArcTan[2.1991 z] == 0,
-2.1 y + 0.0637 ArcTan[2.1991 x] + 2 /Pi ArcTan[2.1991 z] ==0,
-2.1 z + 0.0637 ArcTan[2.1991 x] + 2 /Pi ArcTan[2.1991 y] ==0}, {x, y, z}, Reals],

The out is the same as my put in. Why????
