Hello,
on a Windows server 2012R2 I have installed an Ubuntu 16.04 LTS virtual maschine (Hyper-V) with apache web server and nextcloud 13.
My internet provider gives me a dynamic IP what change sometimes. To reach my computer I have an account at DynDNS.org. With EDDFComputer.dyndns.org I can reach my internet IP. I opened port 443 in my router and forward the port to the ubuntu computer.
Now I updated apache server to get a connection via HTTPS. To get a certificate from Let`s Encrypt I have to execute
certbot --authenticator standalone --installer apache -d cloud.firma.com --pre-hook “service apache2 stop” --post-hook “service apache2 start”
My question is now what domain name I have to write in the command? -d and an extra domain name (where do i get the name from? ) or -d EDDFComputer.dyndns.org ?
