react-native Chrome debug from device is broken? ( Runtime not ready for debugging )

Can anyone suggest things to check for that break Chrome debug on a device? Chrome debug works fine debugging an iOS simulator.

Chrome debug of iOS devices had been working fine for over a month until it stopped working a week or so ago.

I have spent days trying to get Chrome debug working again. I even started all over, with a new "AwesomeProject". No luck.

Does Chrome Debug URL stay same for debugging both device and simulators?

• http://localhost:8081/debugger-ui

Using OS X 10.11.3, Xcode 7.3, iOS 9.3, and react-native 0.22

• MacBook WiFi: 173.17.29.213
• iPad WiFi: 173.17.29.77
• I can ping iPad from MacBook.
• I can run AwesomeProject on iPad and enable live reload.
• I can debug fine in a simulator when jsCodeLocation set to localhost
• I killed Chrome and restarted it, opened http://localhost:8081/debugger-ui
• React Packager is running
• I can set Xcode breakpoints

File: AppDelegate.m

 jsCodeLocation = [NSURL URLWithString:@"http://173.17.29.213:8081/index.ios.bundle?platform=ios&dev=true"]; 

Xcode debug console displays:
