CVX addresses the convexity problem，Why can't I get the global optimal solution even if I change the initial but position?

I think the convex problem has a globally optimal solution. Could you help me sovle the problem?

Please provide all details, No one can answer your question in its current generic form.

If you have a problem for which CVX claims the problem was solved to optimality, and you don’t think that solution is globally optimal, please show us the complete code, preferably with all input data, together with all CVX and solver output, and your evidence that the solution is not (within solver tolerance of being) globally optimal.
