NSURLSession "HTTP load failed kCFStreamErrorDomai

Question

I'm trying to connect my iOS app to an HTTPS Rails app which is currently run on a local host in my network. I can access the site from my browser with https://myIP:3000/display as well as in the command line with a curl request. I'm trying to access it from my app using:

class FirstViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()
        //let url = NSURL(string: "https://another/Sinatra/website/feed")
        let url = NSURL(string: "https://myIP:3000/display")

        let request = NSURLRequest(URL: url!)
        let task = NSURLSession.sharedSession().dataTaskWithURL(url!)
        task!.resume()
    }

When I try to access the sinatra website I have no trouble and can even print out the JSON to the console with the correct commands. However, when I set url to my Rails website I get the following error.

NSURLSession/NSURLConnection HTTP load failed (kCFStreamErrorDomainSSL, -9813)

In addition, I can tell that my localhost Rails app (on the other machine) is not pinged from the iOS app, but is pinged from the browser and curl command.

Any ideas how to fix this?

Answer 1

(Edit - I misread this as 9814, expired cert. I'm not sure how to solve this one, but hopefully my response helps point in the right direction.)

Looks like a cert issue different from the usual "Allow Arbitrary Loads" question.

Brief excerpt from: Apple Documentation - Appendix A: Common Server Trust Evaluation Errors

NSOSStatusErrorDomain errSSLNoRootCert -9813

Answer 2

This is the only solution worked for me... At the end of your AppDelegate.m file, insert the code:

@implementation NSURLRequest(DataController)
+ (BOOL)allowsAnyHTTPSCertificateForHost:(NSString *)host
{
return YES;
}
@end

let config = URLSessionConfiguration.default
let session = URLSession(configuration: config)

Answer 4

Modifying the info.plist worked for me as well.

<key>NSAppTransportSecurity</key>
<dict>
    <key>NSAllowsArbitraryLoads</key>
    <true/>
</dict>

Answer 5

If I understood well, Apple now wants the developers to use HTTPS and TLS 1.2 for network calls.

Temporary, you can add this in your "Info.plist" file :

<key>NSAppTransportSecurity</key>
<dict>
    <key>NSAllowsArbitraryLoads</key>
    <true/>
</dict>

Just have a look to this link, it may also help you : http://ste.vn/2015/06/10/configuring-app-transport-security-ios-9-osx-10-11/

Update : Following some comments the above solution is not anymore working. Here is an updated solution.

1. Go to your Info.plist file.
2. Add a row of Type Dictionary and of Key App Transport Security Settings.
3. In this Dictionary, add a row of Type Boolean, of Key Allow Arbitrary Loads and of Value YES

-

Otherwise you can set Domain Exceptions. This is how to do :

1. Go to your Info.plist file.
2. Add a row of Type Dictionary and of Key App Transport Security Settings.
3. Add a row of Type Dictionary and of Key Exception Domains.
4. Add a row of Type Dictionary and of Key The domain.
5. Add two rows of Type Boolean and of Key NSExceptionAllowsInsecureHTTPLoads & NSIncludesSubdomains with Value to YES.
