All my websites with LE SSL encryption were working fine. I have deleted my Digital Ocean Floating IP as I don’t need it, and now I have only one website working with the LE SSL encryption.
By deleting the floating ip, I changed my ip address. And I had to specify the new IP address on the A records of the domains.
@defacta: It sounds like you may not have correctly configured ServerNames and ServerAliases for each of your hostnames, and Apache is defaulting to using a certificate that does not match the site you are visiting. Can you run:
egrep -r 'ServerName|ServerAlias' /etc/apache2
Also, it would be much easier to assist you if you provide the real hostnames of your sites. It’s harmless to post them here.
dev.anotherwebsite.com is a website for which LE SSL encryption was not working anymore after changing IP address (deleting the Digital Ocean floating IP).
If I don’t show the name it’s because I don’t want a Google search showing this community page.
There’s your problem: You don’t list anotherwebsite.com as a ServerName or ServerAlias, so Apache is using whatever certificate it considers “default.”
