    Marco Burkhardt please double check if you have an AAAA record:

    dig @8.8.8.8 +short -t AAAA example.com

    If you do and the domain does not have an IPv6 assigned make sure the AAAA record is removed.

    Which part was not found?

    Hi Julian,

    I cannot find solution 2 either.

    How can I assign an IPv6 to the domain. Could you please give me a more detailed explanation? That would be great.

    Thank you!

    Hi Renzo,

    DO you see an IPv6 in Tools and Settings > IP Addresses? If you don't that explains why you do not see it in the domain's configuration.

    Do you see the IP in the "ip a" command via ssh? If you do, then hit Reread IP in Tools and Settings > IP Addresses.

     

    It may also be possible that IPv6 is not enabled? https://support.plesk.com/hc/en-us/articles/12377462694807-How-to-enable-IPv6-addresses-on-a-Plesk-server-

    If this does not help please open a support ticket with us https://support.plesk.com/hc/en-us/articles/12388090147095-How-to-get-support-directly-from-Plesk-

    I am getting the same error message, but there is not an AAAA record in the DNS zone. So I cannot remove a non-existent record. Any advice?

    Hi Michael Allen, what is the output of "dig @8.8.8.8 +short -t AAAA example.com". Replace example.com with the real domain.

    Hi Julian,

    I have a problem, I run the dig command and the response is empty, there is no IPv6 assigned.

    Enrique GO in that case make sure there is no IPv6 assigned in Domains > example.com > Hosting.

    Thanks for the response Julian,

    I finally found the problem. Next to the domain I was generating the SSL for 4 other domain aliases. One of them had an AAAA (IPv6) record for a subdomain. The error shown was referring to the main domain instead of the domain alias and that was causing the confusion.
