To fix these errors, please make sure that your domain name was entered correctly and the DNS A/AAAA record(s) for that domain contain(s) the right IP address. Additionally, please check that your computer has a publicly routable IP address and that no firewalls are preventing the server from communicating with the client.

My web server is (include version): Django

The operating system my web server runs on is (include version): Ubuntu Server

My hosting provider, if applicable, is:

I can login to a root shell on my machine (yes or no, or I don't know): Yes

I'm using a control panel to manage my site (no, or provide the name and version of the control panel): No

The version of my client is (e.g. output of certbot --version or certbot-auto --version if you're using Certbot): 1.15.0

Your site needs to be accessible from the world wide web, specifically port 80 for the challenge. At this moment, your host is completely down: no reply with ping, no reply from port 80, no reply from port 443.

Thaks, @Osiris. I will verify with the institution to see whenever the ports are open, and if not open them.
