I followed this tutorial:
Actually I got SSL working for skynfüd.com (skynfüd.com) and pointed skynfud.com at it from Lightsails Hosted Domains... only this second domain wasn't secure yet, so I stupidly followed the tutorial again and broke it. (I now know from a better article I should've just used -d to add a list of domains instead of trying to make a certificate for each).
I used Certbot and followed the Amazon tutorial exactly (but twice).
My question is, can I just delete my Wordpress/Lightsail instance (it's blank anyway) and start a new one, ask for the certificate again but this time just add -d for each domain to add get the SAN/Multi-domain certificate I really need?
Or will this cause my domains to be blacklisted due to asking for another SSL certificate? I keep thinking that if I ask for another certificate whilst one exists and it includes another domain that already has a certificate then the whole thing's going nowhere...?
Many thanks for any help!
