Nope, local connection. No SSL, all inside our in-house router (AirPort Extreme). Up until this morning, all worked great (your app still freezes way too much requiring a close/restart, but that’s another issue). This morning, both iPhones and iPads are unable to connect. The IOS app can’t even find the controller to add it again.
I can still access the controller via Safari on either my Mac or iPhone, so I know the controller is actually still reachable, but that’s it. I’ve tried restarting the controller, the router and the phone. No difference.
for the controller:
App Version: 1.8.0
Firmware: 2.1.8
Hardware Version: 3.0-AC
for IOS:
iPhone 11.4.1, iPAd 12.0 beta
OpenSprinkler app shows version 174
