Thanks for the info. I unknow this. I am going to investigate about it. Then, I wonder me if it is possible to have both, Lets Encrytped and Origin CA together on same server, each one for your respective domain. In this case, I think that should delete Lets Encripted certification only for this domain with Cloudflare DNS, and then to use CA Origin in his place. What is the best way for deleting Lets Encripted certification only for this domain, without to affect to the rest?
