I self-host my websites because, well I’m a computer geek and that’s what we do. Back in the dark ages, we used to pay out the nose for SSL certificates to protect the site content in transit. To this day I won’t deal with GoDaddy because of an issue with that. But then LetsEncrypt was formed by the industry heavyweights and offered free SSL certs for your self-hosting needs.
As I like registering domains on whims, I need to secure them when I bring them up and here’s what you need to do.
First, look up the certificates that you have with:
certbot certificates
Then add the domain you want to at the end of the list, in this case, domain4.com:
certbot certonly –cert-name [CERTNAME] -d domain1.com,domain2.com,domain3.com,domain4.com
