JSON response which you are getting, may be invalid. To check whether it is valid or not, you should test it on www.hurl.com and check for valid json response. — SachinVsSachin, Oct 13 '15 at 06:16

Try to use AFHTTPResponseSerializer instead

manager.responseSerializer = [AFHTTPResponseSerializer serializer];

Because you're using acceptableContentType of @"text/html", I assume you don't need a JSON serializer on response call. So this should be fine for your case.
