Hiya, I have setup a new server following the guideline https://www.howtoforge.com/perfect-server-debian-10-buster-apache-bind-dovecot-ispconfig-3-1/ (like i always do) to see if I could migrate to Debian 10. Now everything is working fine expect one domain. When I change the DNS records to point to my server it doesn't show the default landing page (the apache one) instead it shows the first website on the list of ISPconfig. I know it's confusing so I try to explain. I have DomainA.com which has a website on ISPconfig and all works well. I have DomainB.com which doesnt have a website on ISP config and it shows the default landing page. Then comes DomainC.com which also doesn't have a website and this shows DomainA.com There are no subdomains or aliasdomainssetup and DomainA.com is for client 1 and DomainC.com is for client 4. All unrealted to each other.It's a brand new server with only 5 domains (at the moment, since I stopped when I noticed this happenening) and I can't seem to fix it. I tested with a few new domains, pointed them to the server and it shows the default landing page. I deleted the website, rebooted, cleared cache and tried everything but as soon as I point DomainC.com to this server it shows DomainA.com. It refuses to show the default landing page or (when I add the website to ISPCONFIG) the content in the client/web folder. When I fill up the webfolder of DomainC.com (hoping it wouldn't show the landing page anymore) it still redirects to DomainA.com. Again, there are no redirects what so ever setup in ISPCONFIG. I just uploaded a clean .html file to see if it shows anything if there was a website attached. Tried different extensions as well and all show the default landing page off the server (the var/www/ one) or the content that's uploaded. Just this one domain doesnt. It's not a special domain as well. No numbers or special characters used. I hope someone can help me find this issue because i'm beyond understanding what is happening. EDIT: I just found out that when I go to http://www.DomainC.com/ it shows the landing page and when I go to https://www.domain.com/ it redirects to https://www.DomainA.com/. DomainC.com is not configured in ISPCONFIG whatsoever when this is happening. EDIT2: Just found out this happens with other domains as well. Seems like all HTTPS traffic gets redirected to the first website in ISPCONFIG if there is no domain/website configured. So when i force HTTP it shows the landing page when I force HTTPS it shows the first website of the first client. EDIT3: Double checked, all non configured domains visiting with HTTPS show the SSL certificate and contents of DomainA.com. HTTP is working as intended by showing the landing page. EDIT4: Saw someone stating that if not all sites has * for IP that could cause the issue. Double checked and all Domains have * as IP address EDIT5: It's getting weirder by the day... I just Disabled the first domain on the list (to see what happens) and now all HTTPS visits from non configured domains show the second website on the list...
