Personally, I'd have a look at what certificate nginx is looking at (mine are the default snakeoil ones as it's a fresh install):
I don't know where dehydrated stores the certs /etc/dehydrated/certs I would guess, but I dunno. I only use the official Certbot, just because it matches the rest of our environment so I know what to do when crap hits the fan.
Code:
# grep ssl_cert /etc/nginx/sites-enabled/*
ssl_certificate /etc/ssl/certs/nginx.crt;
ssl_certificate_key /etc/ssl/private/nginx.key;I don't know where dehydrated stores the certs /etc/dehydrated/certs I would guess, but I dunno. I only use the official Certbot, just because it matches the rest of our environment so I know what to do when crap hits the fan.
