Ajax call fails with HTTP status 0 when using Cordova WKWebView plugin on iOS

I've been trying to update my Cordova iOS app to use the new WKWebView pluggable web view, but I have run into an issue where I cannot make ajax calls when it is installed. When I try to make the following call, I get a an error result of HTTP status 0:

return Promise.resolve($.ajax({
        url: 'https://mytestserver.com/settings',
        timeout: 10000 
    }))

I am using Cordova 5.4.1 with iOS platform 4.0.0 and my test device is running iOS 9.2. This code works as expected as soon as I remove the WKWebView plugin and Cordova reverts to UIWebView. I have tried with and without the whitelist plugin (1.2.0).

My config.xml includes:

<access origin="*" />

My index.html CSP tag is:

<meta http-equiv="Content-Security-Policy" content="default-src 'self' data: gap: cdvfile: https://ssl.gstatic.com 'unsafe-inline'; style-src 'self' 'unsafe-inline'; media-src *; img-src *; connect-src https: blob: 'self'; object-src 'self' blob:;">

In index.html the ajax work correctly but in anothers html files didn't, so i had to use index like master page for another files modifying the app and the app work.

Have you read the Limitations section of the doc?

If you are upgrading from UIWebView, please note the limitations of using WKWebView as outlined in our issue tracker.

I think your problem is that WKWebView is affected by CORS

So you have to set Access-Control-Allow-Origin: * on the server
