-(void) testHTTPS {
    AFSecurityPolicy *securityPolicy = [[AFSecurityPolicy alloc] init];
    [securityPolicy setAllowInvalidCertificates:YES];

    AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
    [manager setSecurityPolicy:securityPolicy];
    manager.responseSerializer = [AFHTTPResponseSerializer serializer];

    [manager GET:[NSString stringWithFormat:@"%@", HOST] parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject) {
        NSString *string = [[NSString alloc] initWithData:responseObject encoding:NSUTF8StringEncoding];
        NSLog(@"%@", string);
    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
        NSLog(@"Error: %@", error);
    }];
}

This problem can be due to bad JSON string. By Bad JSON string, I mean that your JSON response might not be starting with the expected characters i.e '[' or '{'. The starting characters must always be anyone of the above two.

Also there might be a chance that your JSON response is embedded in some kind of XML string. This happened to me and for me, it was just bad JSON response like I explained and I solved it by proper parsing.

Check this image. This is what bad JSON can look like.

<?xml version="1.0" encoding="utf-8"?>
<string xmlns="http://tempuri.org/">
[{"Title":"DemoTitle","CreationDate":"06/06/2014","Description":"DemoDescription"}]
</string>

As you can see, JSON is embedded in XML string.**strong text**Also, check your JSON response on this site : http://jsonlint.com/

This will show you if the JSON you receive is valid for parsing or not.

Hope this helps.

You can check your serve Content-Type,If is text/html,you need code this:

 manager.responseSerializer.acceptableContentTypes = [NSSet setWithObject:@"text/html"];

This is the server side error when your server is not responding the JSON response OR Response is not a valid JSON because this error is appears when AF networking library unable to parse the JSON response. Please check it with your server side about the response
