I know this must be the most commonly asked question, but I know very little about the way the web works and less about certificates, so I apologize in advance. This is my first post on this forum.
I self-host a ghost blog on a Linode server, whose domain is mnchrm.co. I had gotten an email about my certificate expiring, but didn’t follow up in time. Now, the site cannot be connected to because of the expired cert. I have root server access of course, but I’m not sure what I need to do to get things back online and prevent this issue in the future.
