Why can't I login to coinhuntr.com? Please help. Thanks.

[sgginc]

When I try to enter:
https//www.coinhuntr.com

I get a message that the page is unavailable.
Tried for 3 days.
Turned off Little Snitch with the same result.
Tried different browsers, same result.

What am I doing wrong?

I have a small balance there and only login once in awhile.

Thanks   ...   Ken
