We'd like to ask you to add Actalis to the list of compatible CAs shown on the https://simple-acme.com/ website
(at the beginning of the "Compatibility" section).

Actalis provides free, unlimited 90-day DV certificates from the following ACME URL, after the user has registered on https://actalis.com

Actalis' ACME service requires EAB authentication. The user's EAB credentials can be found in the customer area of ​​the above-mentioned website.

I remain available for any questions.
