Getting websocket error code 1006 in iOS.

[viniciodeltoro]

I'm using an Actioncable js file to connect to an Actioncable rails server. This actioncable js file uses this nativescript-websockets plugin.
I have been doing connection testing on Android and it works properly, the connection works properly on the web browser as well but when I run it on iOS I get an error like this:
Socket was closed because: code: 1006
This link explains that the connection gets closed abnormally because some incompatibility between the server and the client. I don't really know can can be the issue.
I did post in Stackoverflow since I thought the issue was happening because of the protocols used (actioncable-v1-json, actioncable-unsupported), but even if I don't provide these protocols on the browser test, the connection still works.

Any ideas on what is causing this issue?
Thanks

Does your server by any chance have compression on. Someone reported compression was broken on iOS a while ago; and I haven't had a chance to verify or do anything about it if it is... Disabling compression would fix the issue.

@viniciodeltoro Please share server code. Have you compared between request that is recevied from iOS and request that is recevied from android builds

Sorry I don't have the code anymore I ended up switching to socket.io and using a Node server dedicated for websocket communications only.

I have provided 2 possible solutions here http://stackoverflow.com/a/43952323/319297

My setup is Rails 5 and

    "tns-ios": {
      "version": "2.5.0"
    }

This solution had worked for me.

Had the same issues recently,

In my case it was a problem in WebSocket rfc6455 - different implementation on client and server
and the issue was in dependant iOS lib - PocketSocket

More details here
zwopple/PocketSocket#73

So I simply added

this._headers['Connection'] = "Upgrade";
after
this._headers = options.headers || [];

in websockets.ios.js file

This fix Igor provided has been present in v1.4 or later. If anyone has any more issues with iOS please open a new issue.
