Hi, I have a new installed Debian 9 with ISPconfig. Everything works, But 2 of my websites are not excepting Let's Encrypt. 1 website is running with Lets Encrypt without any problems. Al the 3 websites can I reach with the browser with HTTP. So i suppose that the setup Debian/ISPconfig is working. But what is the reason that the other 2 websites not working with Let's Encrypt through ISPconfig?
