Ionic app stopped connecting to sails API socket connection
Question
I had a working socket connection using sails v0.11.0 and sails.io.js v0.11.5 until approximately one week ago. I've tried reconfiguring my setup to look something like the solution provided here , but still no connection.
ionic index.html scripts loading
<head>
<script src="lib/ionic/js/ionic.bundle.js"></script>
<script src="cordova.js"></script>
<script src="app.js"></script>
<script src="lib/socket.io-client/socket.io.js"></script>
<script src="lib/sails.io.js/sails.io.js"></script>
<script type="text/javascript">io.sails.url = 'http://my_sails_api_ip:1337';</script>
<script src="lib/angularSails/dist/ngsails.io.js"></script>
</head>
Loading the scripts in this order had been working for me for about 6 months. I'm not sure why it stopped.
The error I get in chrome console is;
Failed to load resource: the server responded with a status of 404 (Not Found) http://my_sails_api_ip:1337/__getcookie
I've tried setting 'useCORSRouteToGetCookie = false' as has been suggested on other posts. This results in repeated unsuccessful attempts to make the socket connection as opposed to the single error above.
additional info: My sails api is being ran on an Amazon EC2 instance that "my_sails_api_ip:1337" points to
Edit: I just discovered that if I do ionic serve , to build to my local chrome browser, from the command line instead of ionic run android , to build to my android device, my sails socket connects. I had been successfully connecting from my android device previously.

This was due to my upgrade to Cordova 5.3.3 and effects Cordova 5.xx See this blog post by Nic Raboy https://blog.nraboy.com/2015/05/whitelist-external-resources-for-use-in-ionic-framework/
I had to tweak the meta tag a bit from Nic's to get my websocket to connect as well. Here is what that looks like;
<meta http-equiv="Content-Security-Policy" content="default-src *; style-src 'self' 'unsafe-inline'; script-src * 'unsafe-inline' 'unsafe-eval'">
