Sorry, but hashhunt only runs over http and not https.
Here is a link to access it via http:

Q: I am scared to do anything over http, is this a scam?
This page youy are reading right now is https (check the address bar) so you know it came from me (josh). I am telling you that you
can trust the http site. If you do not believe me, then you should not have trusted that same site over https.
