Hello, I already tried some things, like creating DNS via the wizard and such. Question is: is it possible to have a Let's Encrypt on a Raspberry server which is not connected to the web yet, just local. (or self signed) Let's Encrypt gets un-ticked each time, self SSL seems to work but only for ISPconfig, not for the tempnamewebsite.int, nor phpmyadmin, nor email. Or is this only possible if one has registered a domain at a hosting company and use the DNS credentials or DNS service? If this is not possible then I can stop wasting my time, for now. nb(the goal is eventually to use this Raspberry as a server connected to the web as a start, and then when there are millions and millions of users put it on an external server) Thanks for any help. Best regards, Jerry
Just use a self signed certificate for now, and switch to letsencrypt once you are connected to the web. You can't get a letsencrypt certificate for a hostname that is not in dns, which usually means you have your own domain in use.
