    I am having issues with this. If the domain alias has an ipv6 address in the DNS, it does not work. Is there a way I can assign the ipv6 address to the domain alias? Via ipv6 the challenge is not found by the Lets Encrypt server. 

    In the hosting settings for the domain alias it says (ip is changed by me):

    Web service Web hosting is configured for this domain on IP address 000.000.000.00 

    The ipv6 address is not mentioned. 

    If I go to Tools & Settings and view the IP-adresses. It is also not added to the list op domains under the ipv6 address.

    Have this issue with: Plesk Onyx Version 17.5.3 Update #45

    Still have this issue with: Plesk Onyx Version 17.8.11 Update #5

    Can you please help adding the ipv6 to domain aliases?

    @Remy, is this IP address really can be accessed and pinged?

    Do you mean ipv6 or ipv4?

    It is not possible to assign an ipv6 to a domain alias?

    it should be visible is in the list in Tool & Settings -> IP adresses?

    You can PM me for details.

    @Remy, I mean that the ipv6 address that assigned to a domain alias should be accessible from external network. Check your domain alias for ipv6 availability https://mxtoolbox.com/DNSLookup.aspx

    It is accessible, but not assigned to the alias.

    Can you tell me where I can see if the actual ipv6 address is assigned to the domain alias?

    Remy, ipv6 address should be assigned at Domains > yourmaindomain.com > Web Hosting Access.

    Then, recreate alias for your domain and check section DNS Settings under domain alias, it should contain ipv6 address.

    Thank you, it is working now.

    Still I think the aliases should also be listed in de section: IP-adresses

    Home>IP-adresses:

    'Websites that use shared IP address aaaa:aaa:aaaa:aaa::1.'

    The aliases domains are not listed and counted, this is confusing.

    Hi there, I added an alias (mail.<domain>) for the default subdomain webmail.<domain> based on the following article https://support.plesk.com/hc/en-us/articles/213947325-How-to-set-up-an-access-to-webmail-over-mail-example-com.

    However when trying to (re-)secure the domain & the alias with it, the third row doesn't appear in my case. Would you happen to know why? I'm using the version: 2.5.3-354.

    Hello @Patrick, this is an expected behavior.

    mail.example.com is redirected to webmail.example.com, it is enough to secure webmail.example.com.

    Set of "what else can be secured" is hardcoded.

    Please, leave your suggestion at Plesk User Voice. Popular suggestions will be implemented in future Plesk updates.

    Hi PLESK support, I've problem in securing www.alias-domain.eu in the new wildcard environment. Wildcard works fine in usual. I don't know if I have to configure DNS synchronisation with the main domain, or better set to no sychronisation. In order that the alias.eu will be "securely" redirected with and without www.  to main domain. Actually only the alias without www. (alias.eu) is redirected secure to www.main-domain.com. When I click www.alias.eu browser firefox gives me a HSTS warning.

    @Markus This behavior was recognized as Let's Encrypt extension bug EXTLETSENC-568 which will be fixed in future updates. Thank you for reporting this.
