Without further knowledge about the type of variables, the size of n etc it's hard to recommend anything. The constraints are nonlinear and while there are ways to linearize something like this (e.g. piecewise linear approximation) it's hard to suggest something useful without more details.

For linearizing the nonlinear equations, you can use piecewise modulation. Others, like you are getting an infeasible solution, try to check the boundaries of your variables. Your solution might be out of the feasible region.
