    Hi there,

    This should work, but when I activate "let's encrypt" the domain become un-accessable :)

    Hi, Harry!

    After assigning a Let's Encrypt certificate to a subdomain just go to Tools & Settings > SSL/TLS Certificates

    Find the option Certificate for securing Plesk and click on [Change] button right to it.

    Choose the certificate assigned to subdomain and click OK.

    Hi Artyom,

    It should automatically remove the "Default Certificate" and/or set the Let's Encrypt certificate as default.

    The Let's Encrypt certificate should be automatically applied to mail too (and in such casem if hostname is changed, the certificate should be automtically reissued or at least a warning should be generated)

    The feature that you have reported is yet to be implemented in Plesk, thus I can suggest you take part in our product improvement by referring to the following link:

    The top-ranked suggestions are likely to be included in the next versions of Plesk.

    Hello there;
    I applied the existing SSL certificate and compared it to the following problem.
    Firstly I am having a plesk update problem.
    If this is causing the problem, the YUM update setup can not be done.
    I have encountered this problem since I switched to https connection.

    @Sait I don't think that the issue with YUM update is the consequence of securing Plesk with an SSL certificate. Can you provide more details of YUM update issue?

    @Sait As I can see from the output you provided, it is trying to get plesk-engine package from repo which is not resolvable. Try to disable the repo with and initiate installation of updates again.

    To disable repository you need to find appropriate repo file and edit it:

    1. Execute the following command to find the .repo file:
    grep /etc/yum.repos.d/

    2. Open the file (i.e. some.repo) from the output in editor:
    vi /etc/yum.repos.d/some.repo

    3. Find the section with in "baseurl". It will look like this:


    4. Change "enabled" value to 0

    Trying to follow procedure described above.

    I have a VPS with GoDaddy and the server hostname is in format:
    When I click on the " + Let's Encrypt " button (step 4), it fills that hostname in for me as the "Domain Name", and asks for an email address as well (step 5). So I accept this default (but put in a proper email address) and click INSTALL (step 6).

    This is the error message:
    Could not issue a Let's Encrypt SSL/TLS certificate for Authorization for the domain failed.

    (I've substituted for the actual IP above of course, but that is the format)

    You need to make sure that properly resolves to 12.345.678.90 (to your IP address). For example, use to make sure that the hostname is resolving.
    If it is not, I recommend checking the GoDaddy documentation in order to find out how to make the hostname resolving.
