It would have been better for you to post on your previous thread:
At that thread the problem was that you were trying to finalize an order that included a domain with a badly broken DNS configuration. You said the first faulty domain was no longer in use and was replaced by another one. Yet, the replaced one also had a badly broken DNS config.
The cert you got today did not include either of those problematic domain names. Those were santamoses.com and santarealbeard.com
It looks like the solution was to quit asking for a cert with those faulty domain names 
The 405 is an unusual error for a "finalize". That is more likely a problem in the ACME Client. You never provided the full logs here or when you posted about it (link here) on the acme.sh github. Without the full logs we couldn't say much.
