title: Nginx: [emerg] cannot load certificate after I deleted the certificate
body: <p>I generated an SSL certificate on one of my subdomains. I then tried to <code>delete/revoke</code> the certificate using the command <code>certbot delete</code>. A little terminal menu popped up asking me what certificate I would like to delete. I deleted the one I wanted to delete. Now, when running <code>sudo nginx -t</code> I am getting error messages saying:</p>
  <p><code>nginx: [emerg] cannot load certificate &quot;/etc/letsencrypt/live/app.mydomain.nl/fullchain.pem&quot;: BIO_new_file() failed (SSL: error:02001002:system library:fopen:No such file or directory</code></p>
  <p>I guess the <code>certbot delete</code> command did not fully delete the certificate or something? I am clueless what to do right now...</p>
