XDK 2893 does not handle HTTPS requests from the emulator

Andrea_C_ — Wed, 16 Mar 2016 18:18:25 GMT

Hi to everyone,

I don't know what has happened, but from some days on my personal machine (Ubuntu 14.04 LTS),

XDK started giving me the following errors on HTTPS requests made from the emulator.

Failed to load resource: net::ERR_SSL_PROTOCOL_ERROR https://adress.

This for me is really a big problem, since I can't work on my machine. Is someone having the same behaviour?

Have you tested that project

Have you tested that project on a device? If yes are you facing similar issue over there?

Can you provide some screenshots? Did you try to clear the cache?

What version of Intel XDK are

Elroy_A_Intel — Wed, 16 Mar 2016 22:17:26 GMT

What version of Intel XDK are you using? I also recommend performing an uninstall and reinstall of Intel XDK on your host machine.

Already uninstalled and

Andrea_C_ — Wed, 16 Mar 2016 22:58:30 GMT

Already uninstalled and installed, removed the .config/XDK directory. The version I am mentioning is 2893.

The problem is not shown when using Intel AppPreview or on a built APK.

Here you'll find attach a screenshot of what I get from the Developer Tools window.

Notice that calls to google servers (http vs https) have different results.

Have you tested this on

Hi Amrita,

Andrea_C_ — Thu, 17 Mar 2016 23:22:25 GMT

Hi Amrita,

As said on the previous reply on real devices all works fine. I erased the .config/XDK directory to be sure to have a clean environment.

How otherwise I can clean the cache?

Kind regards.

Hi Andrea,

Amrita_C_Intel — Fri, 18 Mar 2016 17:23:32 GMT

Hi Andrea,

Please refer to this documentation to clear cache: https://software.intel.com/en-us/xdk/blog/remove-xdk-local-data

Amrita,

Amrita,

as for the documentation you sent me, I have already cleaned the cache, since, as said in the previous posts, I removed the .config/XDK folder.

So I now really I don't know what to do.

Andrea -- this is very odd.

Andrea -- this is very odd. My suspicion would be something in your Ubuntu machine got updated that is causing an incompatibility with the node.js code inside the XDK that talks to the openssl (or whatever is being used to manage the https requests) in the Linux system. Did you apply some updates to your Ubuntu box just before this happened?

Can you try running the XDK on a "fresh" Ubuntu 14.04 system that does not include any Ubuntu updates?

Hi Paul,

Andrea_C_ — Sun, 20 Mar 2016 09:42:47 GMT

Hi Paul,

I have a lot of updates on my machine and, previously XDK 2893 was working fine. I will try to install it in a clean virtual machine with a fresh 14.04. Most probably the problem is caused by some updates, but I really don't know the root cause.

Please keep me posted.

PaulF_IntelCorp — Mon, 21 Mar 2016 02:24:42 GMT

Please keep me posted.

I tried with a fresh install

Andrea_C_ — Mon, 21 Mar 2016 11:26:03 GMT

I tried with a fresh install of XDK on a 14.04 LTS Virtual machine and everything works fine.

So most probably there is something messed up with my system, but I can't figure out what it is. I can't understand why everything works (all browsers, including Chrome), with the exception of XDK.

I'll try in the next weeks to install a new version of Linux from scratch, hoping that the issue will go away.

Andrea -- I've filed a bug

PaulF_IntelCorp — Mon, 21 Mar 2016 17:42:55 GMT

Andrea -- I've filed a bug report, to at least look into the idea that OpenSSL updates to Ubuntu might be interfering with the underlying node.js system. If you find more precise info, that would be useful.

Paul,

Andrea_C_ — Mon, 21 Mar 2016 20:22:41 GMT

Paul,

I have made 2 experiments:

1) Clean install and running XDK. SSL is OK

2) Update all the packages and running the XDK: SSL is OK.

So maybe I have something messed up with my system, but it's really really strange.

Thanks for the feedback,

PaulF_IntelCorp — Tue, 22 Mar 2016 03:05:25 GMT

Thanks for the feedback, Andrea. I'm alerted whenever you post to this thread, so if you do find some clues I'll let engineering know.

I reinstalled Linux (16.04)

Andrea_C_ — Fri, 01 Apr 2016 22:31:12 GMT

I reinstalled Linux (16.04) from scratch.

Still HTTPS connection do not work, but I noticed that:

1) $.get("https://maps.googleapis.com/maps/api/geocode/json")

Fails with: et::ERR_SSL_PROTOCOL_ERROR

2) $.get("https://api.twilio.com/2010-04-01")

Is OK (Notice it's still HTTPS).

Could you please test this? I really don't know what to do.

Andrea -- are you seeing this

PaulF_IntelCorp — Mon, 04 Apr 2016 15:55:10 GMT

Andrea -- are you seeing this only in the Emulate tab or also in App Preview and the Debug tab and ??? The .../json part of that google maps URL makes me think this is related to some issues we've been seeing with App Preview and the Debug tab that are resulting in an error return but the JSON data is actually being returned (along with some error tags).

No Paul,

Andrea_C_ — Mon, 04 Apr 2016 16:09:46 GMT

No Paul,

on AppPreview (Debug tab) everything works fine, even before I reinstalled the system from scratch.

The issue is present only in the emulator. For some reason it's like the SSL certificates from the google servers are no more considered valid, but the ones from other servers (e.g. Twilio) are considered valid.

Can you please simply add the jquery script in a empty project and launch from the emulator debugging tab " $.get("https://maps.googleapis.com/maps/api/geocode/json") ?

Andrea -- are you still

PaulF_IntelCorp — Mon, 04 Apr 2016 16:31:15 GMT

Andrea -- are you still running 2893 or are you now seeing this on 3088?

I was able to reproduce on my

PaulF_IntelCorp — Mon, 04 Apr 2016 16:34:06 GMT

I was able to reproduce on my Mac running 3088. I've alerted engineering and have assigned a bug to this. Will also try a few other experiments.
