Hello to all. maybe you can help me to find a solution for this: I am using an ISPConfig 3.1 installation on Debian Buster minimal. I have got DNSSEC setup. Everything so far is working fine, except if I want to setup a subdomain website with its own webspace, which does not resolve (Server not found error). I did add an A record to my DNS to point it to my IP host: subdomain IP: 22.214.171.124 TTL: 3600 Active: ticked ( I also tried with host: subdomain.domain.tld. when host: subdomain did not work) I then created a new website with domain: subdomain.domain.tld and the most basic settings as follows: Server: server1.mydomain.com Client: client IPv4-Address: * IPv6-Address: Domain: subdomain.domain.tld Document Root: /var/www/clients/client1/web2 Harddisk Quota: -1 Traffic Quota: -1 CGI: No SSI: No Perl: No Ruby: No Python: No SuEXEC: YES Own Error-Documents: YES Auto-Subdomain: None SSL: No Let's Encrypt SSL: No PHP: Disabled Web server config: Active: YES BTW if I redirect subdomain.domain.tld to domain.tld/subdomain that works just fine, but I would like to have an own webroot (like /var/www/clients/client1/web2/web/ ) for subdomain.domain.tld apart from the webroot of domain.tld ( (like /var/www/clients/client1/web1/web/ ) I have tried to do service bind9 reload and service bind9 restart, but to no avail. So right now I am investigating where I missed something or if this is a feature of ISPConfig that I am not understanding rightly could you point me to a good tutorial (apart from the ISPConfig3.1 tut, which I already have consulted - hopefully not omitting some info that would make this thread uneccessary. Thank you!
