When I installed ISPConfig, I configured it to use https access. I also created a certificate during installation that matches the hostname of the server, so when I as admin access ISPConfig everything works fine. However, for any client sites, when they access their ISPConfig using for example https://www.myclient.com:81/ they will get an error message saying there is a mismatch between the certificate and the name of the site. Is there a way to avoid that? - or should I just configure it to use http access instead to avoid the certificate mismatch?
