Getting CFNetwork SSLHandshake failed (-9806) error

Question

I am trying to call my url using

NSDictionary *landingDetails=[appDelegate landingPage];

        NSString *devinf=[UIDevice currentDevice].systemVersion;
        NSString *appVersion = [[[NSBundle mainBundle] infoDictionary] objectForKey:@"CFBundleVersion"];

        NSMutableDictionary *reqDict=[NSMutableDictionary dictionary];
        [reqDict setObject:@"refillByScan" forKey:@"appId"];
        [reqDict setObject:@"extest1" forKey:@"affId"];
        [reqDict setObject:[landingDetails objectForKey:@"token"] forKey:@"token"];
        [reqDict setObject:@"0124400-59382" forKey:@"rxNo"];//medication or prescription id
        [reqDict setObject:@"appName://handleControlFromScanRefill" forKey:@"appCallBackScheme"];
        [reqDict setObject:@"callBackAction" forKey:@"appCallBackAction"];
        [reqDict setObject:@"chkExpRx" forKey:@"act"];
        [reqDict setObject:@"" forKey:@"trackingId"];
        [reqDict setObject:devinf forKey:@"devinf"];
        [reqDict setObject:appVersion forKey:@"appver"];

        NSString *landingUrl=[landingDetails objectForKey:@"landingUrl"];//my url
        request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:landingUrl]];
        NSString *jsonRequest = [reqDict JSONRepresentation];
        NSLog(@"jsonRequest is %@", jsonRequest);
        NSData *requestData = [NSData dataWithBytes:[jsonRequest UTF8String] length:[jsonRequest length]];

        [request setHTTPMethod:@"POST"];
        [request setValue:[NSString stringWithFormat:@"%d", [requestData length]] forHTTPHeaderField:@"Content-Length"];
        [request setHTTPBody: requestData];

        con=[[NSURLConnection alloc]initWithRequest:request delegate:self];
        [con start];

I am getting this error in my log

Answer 1

FWIW: I got the same error number and it was due to an expired certificate, so this is another potential source for the issue.

Answer 2

There is a bug on iOS 8 when using a certificate with hash function SHA512, better use the SHA256. I stuck with this error for weeks.

Answer 3

Normally when I get CFNetwork SSLHandshake failed -(*) Its because of my local wifi network (device is connected to network but not the internet)

Try it again on another network (3G is the quickest solution for me)
