Certbot installation not working on nginx

Question

I am trying to install a certificate with certbot onto my subdomain. It says that I have no server_name directive in my nginx config but I do, and I did nginx -t and it said the config was ok.

This is the command line output from certbot

    You have an existing certificate that has exactly the same domains or certificate name you requested and isn't close to expiry.

    Could not automatically find a matching server block for subdomain.website.com. Set the `server_name` directive to use the Nginx installer.

    IMPORTANT NOTES:
     - Unable to install the certificate
     - Congratulations! Your certificate and chain have been saved at:
       /etc/letsencrypt/live/subdomain.website.com/fullchain.pem
       Your key file has been saved at:
       /etc/letsencrypt/live/subdomain.website.com/privkey.pem
       Your cert will expire on 2021-01-01. To obtain a new or tweaked
       version of this certificate in the future, simply run certbot again
       with the "certonly" option. To non-interactively renew *all* of
       your certificates, run "certbot renew"

This is my nginx configuration.
