WD General Network Error 500, iPhone App, HELP!

Hi again, sorry for the delay. Have you tried doing a System only restore? If that doesn’t work you can try a full factory restore, but note that this one will delete all of your files. If the problem continues after this I would recommend to contact support directly, they can help you narrow down the cause of the problem.
