I noticed something a few days ago when visiting one of my sites and my browser
said the cert was expired.
I checked the cert with certbot, which said it was not expired (recently
renewed). Then checked remotely with openssl, which said it's expired. I
verified that nginx was configured properly to use the correct cert, then
finally restarted nginx, which solved the issue.
So I'm assuming that nginx reloads the cert at some interval, but not each
connection (which makes sense). The cert had expired within a few hours of me
getting the expired message, but had already been renewed. I've never noticed
this with my sites since I probably haven't just happened to visit at just the
Anyone else noticed this, or know how often nginx checks the cert?
