An unexpected error occurred:
Error creating new order :: too many certificates (5) already issued for this exact set of domains in the last 168 hours: holonext.io,www.holonext.io: see Rate Limits - Let's Encrypt
My web server is (include version): Ubuntu 20.04 on AWS
and ı want to use my old fullchain.pem and privekey.pem file how can ı do this using nginx and cerbot without creating new certificates?
It would be best if you could restore the /etc/letsencrypt/ directory to its original state. Certbot also requires a renewal configuration file and specific symbolic links in certain directories to function properly
That said, you could also just store your found certificate/private key somewhere and configure nginx as @9peppe mentions and when it would be time to renew the certificate (30 days before expiry), run Certbot again to get a "new" certificate, which would overwrite the nginx configuration (if run with the --nginx plugin and withoutcertonly).
