I'll try to be as clear as I can. In this server I have debian 8. I'm trying to make a Let's Encrypt SSL Wildcard domain. I got it for the main domain: "fakturo.org", but no for "yipies.fakturo.org" that shows the clasic "Warning: Potential Security Risk Ahead" The website config is: After install 3.14p2 and edit the website SSL tab, two records CAA was inserted in it's DNS Zone. Number 2 Can be edited Well. I checked Use Wildcard SSL but nothing changed. Number 1 give an error on regex when I try to save. This is the first view when I go to edit. Then I check Use Wildcard SSL and save and gives that error. name_error_regex and changes the readonly field from '*.fakturo.org' to just '*' (The '*' seems to be the problem.) Can you point me in the right direction to get Let's Encrypt wildcard SSL ?
