Let's Encrypt version 1.0.1 error

    For first, time will solve problem, with your changes users would create tickets why letsencryt is not available for domain xyz (reverse problem) XD About the other, I'm still a bit against it but it seems that lots of users are not implementing www CNAME for subdomain, so I'm fine removing www support for subdomains. If someone needs it, he still can implement it :D

    But my unmöglichefirmen.de page no longer went previously only since going I HSTS includeSubDomains Directive made active domain.

    my System :

    - Distribution: Debian | Release: 9.13 | Codename: wheezy
    - i-MSCP Version: i-MSCP 1.5.3| Build: 20181208 | Codename: Ennio Morricone
    - Plugins installed: ClamAV (v. 1.3.0), Mailgraph (v 1.1.1), OpenDKIM (v 2.0.0), SpamAssassin (v 2.0.1)
    - LetsEncrypt (v3.3.0), PhpSwitcher (v 5.0.5), RoundcubePlugins (v 2.0.2)YubiKeyAuth 1.1.0

    I did not understand. Please explain a bit more clear
