Validation of the required challenges did not complete successfully, Invalid Response

Hi,

I’m having problem to generate certificate, but the test is OK.
Pointing to IIS root for local testing purpose, no blocking for port 80/443.
Any clues?

The URLs get redirected by HTTP 302 responses to a domain reseller page at the base domain.

Seemingly you don’t own the domain?

Also when I use Let’s Debug it says your server types is DOSarrest, so if that’s some kind of http proxy that it needs to know to forward requests to the server running Certify.
