When I check my site against SSL Labs’s testing, I see 2 certificates and I’m not sure why.
The site is gdb-tutorial.net. Certificate #1 matches that:
(You’ll see I’m using that certificate for gdb-tutorial.net, static.gdb-tutorial.net, and www.gdb-tutorial.net)
However, there is also certificate #2 for www.chrisblume.net. I am not sure why this is showing up.
This is another domain on this server. But it isn’t from RDNS. That would be a different domain.
I’m not sure how I messed this up. But I completely deleted /etc/letsencrypt/live/gdb-tutorial.net/* to create a new certificate a while ago which included the subdomains. The double-certificate problem existed before and appears to still exist.
Any ideas why that second certificate is listed and how to remove it?
