We are using let's encrypt with BuyPass to issue certificates for our lower level environment. It has been working well for the past few months. However, starting a couple days ago we are receiving the following error: 

Create new order error. Le_OrderFinalize not found. {"type":"urn:ietf:params:acme:error:compound","title":"Forbidden","status":403,"detail":"Some of the identifiers requested were rejected ","instance":"/acme/new-order","subproblems":[{"type":"urn:ietf:params:acme:error:rejectedIdentifier","title":"Forbidden","status":403,"detail":"Domain is rejected as high-risk","identifier":{"type":"dns"}},{"type":"urn:ietf:params:acme:error:rejectedIdentifier","title":"Forbidden","status":403,"detail":"Domain is rejected as high-risk","identifier":{"type":"dns"}},{"type":"urn:ietf:params:acme:error:rejectedIdentifier","title":"Forbidden","status":403,"detail":"Domain is rejected as high-risk","identifier":{"type":"dns"}},{"type":"urn:ietf:params:acme:error:rejectedIdentifier","title":"Forbidden","status":403,"detail":"Domain is rejected as high-risk","identifier":{"type":"dns"}}]}

We use a common domain structure to identify which client is is under our main company domain which is client_domain.our_company_domain.com.

I need to get this resolved as soon as possible. Any input would help. How can we ensure they are not deemed as "high-risk".
