I am a newbie in this. First time I try to install the SSL myself. I have access to root. My server is a server cloud. I tried to follow a tutorial to install Let’s Encrypt but I got this binding issue at the end of the process. What should I do from there ?
My domain is: serrurier-secours.ch
I followed this tutorial for a Debian server : https://linode.com/docs/security/ssl/install-lets-encrypt-to-create-ssl-certificates/
I ran this command:
sudo -H ./letsencrypt-auto certonly --standalone -d serrurier-secours.ch -d www.serrurier-secours.ch and then agreed with terms
It produced this output: Obtaining a new certificate
