Obtaining a new certificate
Performing the following challenges:
http-01 challenge for api.research-ranger.com
Using the webroot path /usr/share/nginx/html for all unmatched domains.
Waiting for verification...
Cleaning up challenges

IMPORTANT NOTES:
 - Congratulations! Your certificate and chain have been saved at:
   /etc/letsencrypt/live/hirooooo-lab.com/fullchain.pem
   Your key file has been saved at:
   /etc/letsencrypt/live/hirooooo-lab.com/privkey.pem
   Your cert will expire on 2020-06-15. To obtain a new or tweaked
   version of this certificate in the future, simply run certbot-auto
   again. To non-interactively renew *all* of your certificates, run
   "certbot-auto renew"
 - Your account credentials have been saved in your Certbot
   configuration directory at /etc/letsencrypt. You should make a
   secure backup of this folder now. This configuration directory will
   also contain certificates and private keys obtained by Certbot so
   making regular backups of this folder is ideal.
