I get the same error if I try to access my ip-100 from rainwise, most routers do not like you going out and back in to a local device so I access my ip-100 by going directly to the local private network address. WU has been weird lately with my setup also with gaps and missing data and the barometer reading zero which my console does not see nor does my cc-3000 see it, so I'm 99% sure it's a WU problem...
