    I have created an alias for the domain The domain is not redirected to my nameservers yet. After loading I will get the message ERR_CERT_COMMON_NAME_INVALID with another domain name After clicking that I still want to go to the page, I am redirected to another website - Where could the problem be? is a site created in ispconfig

    Is this WPMU? My preference would be to use alias domain with vhost so that each domain / subdomain can have their own LE certs.

    But I also read that you can also do the same without vhost i.e. with only one master LE certs which covers up to max 100 domains / subdomains.

    I never got the later to work with my nginx web server so I sticked to my preference.

    For your problem, I guess you just have to make sure the other domain / subdomain is included in the master domain LE certs so you won't have the said error(s).

    I'm sorry, but even after reading the instructions, I don't know what's wrong. I have three domains registered.
    First domain (DNS to my servers)

    Second domain (DNS to my servers)

    Third domain (DNS is not on my servers)

    Alias (main domain:

    I use Nginx
    Is there any setting that is wrong?
    My goal is to get an alias for a domain that is not yet redirected.

    Thank you for your help

    Add the alias domain to the LE cert. You have disabled that currently. And disable the * subdomain, set it to www. (ISPConfig currently does not support LE wildcard certs)
