NSURLConnection GET request returns -1005, “the ne

Question

I am trying to make a simple GET request using NSURLConnection in XCode 6 (Beta7 2) on iOS 8 SDK, which is failing with "Code 1005, the network connection was lost". The call fails when I try to fetch http://www.google.com or a few other sample pages from the web, but succeeds if I make a request to a simple HTTP server on localhost (python -m SimpleHTTPServer). I have also tried using AFNetworking library (2.4.1) - URLs that fail with NSURLConnection also fail with the library.

Here's my code -

NSString * url = @"http://0.0.0.0:8000";
// NSString * url = @"http://www.google.com";

NSLog(@"URL : %@", url);

// Mutable is probably not required, but just in case it REALLY WANTS me to set HTTP method
NSMutableURLRequest *theRequest = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:url]];
[theRequest setHTTPMethod:@"GET"];

NSURLResponse *urlResponse = nil;
NSError *error = nil;

NSData * data = [NSURLConnection sendSynchronousRequest:theRequest
                                      returningResponse:&urlResponse
                                error:&error];

if (error == nil) {
    NSString *response = [[NSString alloc] initWithData:data encoding:NSASCIIStringEncoding];
    NSLog(response);
} else {
    NSString *response = [[NSString alloc] initWithData:data encoding:NSASCIIStringEncoding];
    NSLog(@"%@", [error userInfo]);
}

Simple & sample solution, tested many times, working perfect.

//Check response error using status code, and if you get -1005 then call that api again.

                if let strErrorReasonCode : Int = response.response?.statusCode {
                           if authentication_Errors_Range.contains(Alamofire_Error) {
                                self.POST(urlString, paramaters: paramaters, showLoader: showLoader, success: { (responseObject) in
                                    if response.result.isSuccess {
                                        if let value = response.result.value {
                                            let dictResponce = self.isValidated(value as AnyObject)
                                            if dictResponce.0 == true {
                                                success(dictResponce.1)
                                            }
                                            else {
                                                failure(dictResponce.1)
                                            }
                                        }
                                    }
                                }, failure: {_ in
                                    failure(jsonResponce)
                                })
                            }
                 }
