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

Question

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:
2016-03-31 08:02:12.286 [error][tid:com.facebook.react.RCTBridgeQueue][RCTWebSocketExecutor.m:85] Runtime is not ready for debugging.
- Make sure Packager server is running.
- Make sure Chrome is running and not paused on a breakpoint or exception and try reloading again.

You're close, one more step and works for me at the moment after facing exact situation:
"To debug on a real device:
On iOS - open the file RCTWebSocketExecutor.m and change localhost to the IP address of your computer. Shake the device to open the development menu with the option to start debugging. [1]"
