I solved mine, doing two things.
Factory Reset to device
Reset to Router
I think i was "dumb" and should have done it in REVERSE, so if i were you i would reset the router. Simple step is unplug it and plug it back. IF necessary, there is a way to reset it...in my case it was a call to the ISP.
REMINDER...i had several apps on same device and several devices worked fine, i think it was SOME MISCONFIGURATION on the network that was critical to my device and SWOGH (the combo), but irrelevant to other apps/devices.
