UIWebView + Sharepoint + NTLM Auth - I get Stream

I have been working on an App that has a simple UIWebView in it that displays a Sharepoint site. I originally thought the NTLM authentication would be an issue but as it turns out that is really straight forward. However, ever since iOS8 my app has been spamming "Stream is sending an event before being opened" over and over again in my log to the point that the page really never can load.

I originally thought it was something I was doing so I created a small app (below) to remove any weirdness my other app may have had but unfortunately I get the same issue. I guess my main issue is I don't know where to even start to look to find an answer to this one. The Internet has some mention of this but no clear resolution like [webView dontDoThat]. :D

I am playing around with adding the connection to the run loop manually, you will see this in the code. I have tried every way I know how to create the connection but this is the most recent try.

I start out handing the SSL challenge because my cert is not valid for the domain, then I get the NTLM challenge and send in the hard coded username and pass as a test. It partially loads the site but finally gives up loading all the resources in what I assume is this error. Theories welcome.

Any help appreciated! - Greg Frame
