CVX’;s Successive Approximation method failed. It didn’t declare the problem to be infeasible.
First, improve the numerical scaling of input data, by changing units, so that all non-zero input data is within s small number of orders of magnitude of 1.
Use Mosek as solver if available to you; otherwise, follow the advice at CVXQUAD: How to use CVXQUAD's Pade Approximant instead of CVX's unreliable Successive Approximation for GP mode, log, exp, entr, rel_entr, kl_div, log_det, det_rootn, exponential cone.
