works you need to merge Terminal  cat certificate.crt ca_bundle.crt >> certificate.crt

server { listen 80;


listen               443 ssl;


    ssl                  on;
    ssl_certificate      /home/cert/certificate2.crt;
    ssl_certificate_key  /home/cert/private.key;

  server_name site.com www.site.com;

  location / {
      proxy_pass http://localhost:3000/;
      proxy_set_header Host $http_host;
      proxy_set_header X-Real-IP $remote_addr;
      proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
      proxy_set_header X-Forwarded-Proto $scheme;
  }
