Tell us what’s happening:
I can’t get the get the challenge to be completed. For whatever reason
the url that is being used to doesn’t recognize my error response as valid. Do I need to put a status or something?
Okay. But I’ve ran into a slight problem. john-doe.org resolves to 83.243.58.246 in the IPv4 family and to ::ffff:83.243.58.246 in the IPv6 family. I look up the host name and if it doesn’t resolve it; then I give out the invalid URL JSON.
