1395423 - Cannot connect from WebIDE to Nightly for Android with WiFi

Status: RESOLVED WORKSFORME

(DevTools Graveyard :: WebIDE, defect, P2)

Description

[Masayuki Nakano [:masayuki] (he/him)(JST, +0900)(away until 10/14)]

STR:

1. Allow to debug via WiFi in the settings of Nightly for Android.
2. Open WebIDE on Nightly on Desktop (I tested on Win10).
3. Try to connect to the Android device from its right pane.

Actual result:
I see yellow information bar, "Operation failed: Connecting to XXXXXX".

In the Browser Console, I see:

> Connection status changed: connecting  app-manager.js:156
> Exception { name: "NS_BASE_STREAM_CLOSED", message: "Component returned failure code: 0x…", result: 2152136706, filename: "resource://gre/modules/commonjs/too…", lineNumber: 330, columnNumber: 0, data: null, stack: "onInputStreamReady@resource://gre/m…", location: XPCWrappedNative_NoHelper }  connection-manager.js:324

I *can* connect to Firefox 55 and 56 Beta with same environment. So, this could be a regression of 57.

Ah, my Android version is 7.1.1 and Windows 10 is build 16251 (Insider build, slow ring).

Thanks for the report and sorry for the delay!

I'm having trouble reproducing the issue here.  When I test Nightly 57 (20170919) on Windows 10:

1. The device appears in the right pane
2. Choosing is triggers QR code to appear in WebIDE and scan prompt on the phone
3. Selecting scan on the phone and hovering the QR code finishes the setup
4. Connection is now ready

Are you still seeing this with the latest Nightly?

Yeah, I also don't reproduce this bug anymore.
