Hello, My issue is this: If have setup a ispconfig 3.1 for my server and after that i changed self-signed ssl to ispconfig created domain with let's encrypt. But because ispconfig install is designed to work on all domains, i get stupid ssl warning because of the domain not matching the certificate. So if my intended ispconfig domain is server1.example.com:8080. Then i type server2.example.com:8080, which points to same ip. It's shows ssl warning(offcourse). Is there any way make ispconfig panel reachable only to server1.example.com domain and all other domains pointing same ip and port 8080 would be either redirected to server1.example.com:8080 or redirect to main domain with standard port at example.com ? Allso, is there anyway to make ssl cerficate permanent, when upgrading ispconfig itself?
