I installed lets encrypt on my Raspberry pi 3 board running apache2. Certbot ran fine and I was about to get a cert. The site works great.
I am going to change my dynamic dns name to a new one. Every time I try to reinstall a cert, it tells me there is an error. I used the --installer apache switch to get this done the first time.
What would be the right way to get a new cert with the new domain name?
