Hi we have a Dedicated Root Server and have Install Ubuntu + ISPConfig 3
We use it for our Onlineshops and bit now 11 Shops with 11 Domains work in ISPConfig, now i regestry a new Domain and after 3 days i add it to ispconfig as normal Webside Domain.

The New Domain only show the Content from the first Domain in ISPConfig and not show the welcome content from the new Domain.
I Have upload on the new Domain by FTP the Wordpress Installation and self this he not show.
All Domains run with the same IP and not *
Webserver is Apache2 without nginx.
We use SSL and Let's Encrypt SSL

I found out that by /etc/apache2/sites-available/sitename.vhost.err and when i change this to sitename.vhost then the webside work but with out a ssl certification

 

I found out that the Certbot not working now i have fix it and reinstall certbot and all run well.
