    Hey together,

    after a new setup i try'd to setup these sites over Websites -> Create new Website:
    web.-, mail.-, cloud.-, support.-, wiki.-, community.-, domain.tld

    all just working fine with ssl, le ssl, http to https - but not mail. Rewrite and SSL ok - if i try to activate le and save ispconfig show the task, after some time its finished - checking cert showing the newest created le ssl (cloud.domain.tld).

    all A Records showing to the master (web)
    DNS Lookup is good
    all http to https rewrites working fine
    All Domains have active SSL and rewrite and showing with the ip to "*"
    nothing in le cert log files - rlly - nooothing for this setup try
    nothing in /var/log/ispconfig/*

    Debian 9.5 + PHP7.0 - 5 Multi Server Setup

    Any idea out there?

    Best regards

    Found something trippy in dmesg:

    You can use the ISPConfig debug mode to see in details why a domain is excluded from LE.

    The subdomain is excluded as it is not reachable from the server. ISPConfig does what LE is doing to verify the domain, it puts a token file into the LE token directory and then it tries to reach it by http. When dns is ok and you are sure that it propagated to all dns caches, then you might check if this subdomain is set in the /etc/hosts file on this server and pointed to a wrong IP.

    In the /etc/hosts its showing to the mail gateway which is rlly mail.domain.tld - but the A Record showing to web which should be the relay for the gateway? (like deb8 multiserver setup).

    Okay - now i know why it would not work :D

    I think if the hosting service goes online its should be a wildcard ssl cert like PositiveSSL - Wildcard SSL from comodo and just LE for customers ^^?

    Wildcard ssl is not yet supported by ISPConfig if that is what you mean. Some tips are discussed in here.

    When the subdomain is used on the mail server only (for postfix and dovecot) and your mail server is not running a web server like apache or nginx, then you could e.g. create the ssl cert for the mail subdomain on the mail server with certbot manually by using the standalone mode. But standalone mode can only be used when there is no other web server on that system.
    Frankenstein and ahrasis like this.

    So it's ok that the a record showing to web.domain.tld - i can create the certificate locally on mail.domain.tld (mailserver) (when on the mailserver is no running webserver) with certbot standalone - did I understand that correctly?
