Typically, Newton-based techniques are local continuation methods and the initial guess is very important. In most of the cases, I have used (highly non-linear as well) N-technique they have converged unless you have cases like turning points, bifurcation points, and so on. Since you already have an idea of the solution, I suspect that the problem could be due some small error in your Jacobian. In most of the cases, double-checking your Jacobian will be your worthwhile.
