The problem comes from response parsing. You are trying to de-serialize a JSON reponse (which MUST be contained in either a NSArray or NSDictionary) however your response is none of the above (Most likely a simple string).

Also, try to set the "allow fragments" to the response serializer.

AFJSONResponseSerializer *responseSerializer = [AFJSONResponseSerializer serializerWithReadingOptions:NSJSONReadingAllowFragments];
