Hi! I ve two vps, two plesks, two subscriptions (domain.com and mail.domain.com). One plesk is for the web (Wordpress), the other for mails. I ve let's encrypt in both subscriptions. In the web vps all works fine, but, in the mail plesk I've to move the ssl cert every three months -created with the hosting plesk - to the mail subscription cause the acme challenge cannot be resolved. Some idea how can avoid that? is very tired being pending of the expiration date of the certificate. Thanks!
