Checking one of your domains there is no answer - https://check-your-website.server-daten.de/?q=edge1.colheli.com
There are some certificates created:
But checking your urls - Grade V:
You need a working port 80 / http. Same with all of your other domains.
But that’s a configuration problem of your system you have to fix before you can create a certificate.
PS: The edge2 has the “next” ip address. But the non-www has a completely different ip address.
Is there a redirect to one of the edge-Domains?
Normally: If you create a SAN-certificate via http-validation, all domains have the same ip address. I don’t know if your client supports such a configuration with different ip addresses.
It’s possible to create redirects. But I don’t see if this is your setup.
