Hi. I've set up a first site (where ISPConfig portal is) as DOMAIN1, which I've checked "SSL" and "Lets Encrypt SSL" options. I then set up a new Client and its first site, DOMAIN2 and checked same SSL options. As soon as it finished configuring, I'd go back to DOMAIN1, my browser complained of "Your connection is not private" problem...upon examining the SSL certificate, it shows that it's using DOMAIN2's certificate. If I go to DOMAIN2 configuration and unchecked those two boxes and go back to DOMAIN1, then it won't complain...so this problem is readily reproducible. Thoughts/assistance is greatly appreciated.
