real nonlinear equations solver

I am trying to solve three real nonlinear equations for three variables. I have tried 'fsolve' but with most of the initial guesses, it gives the 'exitflag=-2' that is

'fsolve stopped because the relative size of the current step is less than the
default value of the step size tolerance squared, but the vector of function values
is not near zero as measured by the default value of the function tolerance.'

I haven't been able to find solution with this. I wanted to know if there is any other suitable method for this case to solve nonlinear equations,
