Server is throwing SSL certificate error.
For the sake of testing, you can add the following code to the appDelegate:
+ (BOOL)allowsAnyHTTPSCertificateForHost:(NSString *)host {
return YES;
}
This will bypass the SSL error
Note: works for NSURLConnection & UIWebView, but not for WKWebView
Edited:
For iOS 9, above procedure don’t work. Add the following snippet in info.plist:
<key>NSAppTransportSecurity</key>
<dict>
<key>NSAllowsArbitraryLoads</key>
<true/>
</dict>
