Hey there!
One of our customers is trying to issue a certificate for [subdomain].samsung.ch for a project in Switzerland. When trying to reproduce it, I get the following error:
{"type"=>"urn:acme:error:rejectedIdentifier", "detail"=>"Error creating new authz", "status"=>400}
Could it be that samsung.ch is on your blacklist? Is it possible to remove it from there?
Thanks!
