Hello everyone, I just switched to ispConfig, it's installed, everything is fine. On the other hand, I'm a bit confused about the default panel dns configuration. I have declared at my web host a type A domain > srv-b.democrasite.com I point it to my VPS at 220.127.116.11, it's ok, I'm on the panel. Following the tutorial, I do "hostname -f" which sends me back srv-b.democraite.com As I'm not super technical, I'd like to know already if I've set up the panel and DNS zones correctly. For the moment I think it's easier for me to leave the DNS management to my registrar and only manage the Zones in ispConfig. At my registrar for DNS I have : dns200.anycast.me ns200.anycast.me My question is ; did I correctly configure ispConfig to have a certificate let's encrypt on the main site = ispConfig_default_panel Thank you for your help.
