Error getting validation data

Help

Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. crt.sh | example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.

My domain is: panel.hajsori.xyz

I ran this command: certbot certonly --nginx -d panel.hajsori.xyz -v

It produced this output:

root@hajsori-debian-server:/home/hajsori# certbot certonly --nginx -d panel.hajsori.xyz -v
Saving debug log to /var/log/letsencrypt/letsencrypt.log
Plugins selected: Authenticator nginx, Installer nginx

http-01 challenge for panel.hajsori.xyz

Certbot failed to authenticate some domains (authenticator: nginx). The Certificate Authority reported these problems:
  Domain: panel.hajsori.xyz
  Type:   connection
  Detail: myIp: Fetching http://panel.hajsori.xyz/.well-known/acme-challenge/code: Error getting validation data

Hint: The Certificate Authority failed to verify the temporary nginx configuration changes made by Certbot. Ensure the listed domains point to this nginx server and that it is accessible from the internet.

Cleaning up challenges
Some challenges have failed.
Ask for help or search for solutions at https://community.letsencrypt.org. See the logfile /var/log/letsencrypt/letsencrypt.log or re-run Certbot with -v for more details.

Hello @Hajsori,

The HTTP-01 challenge require access to Port 80 from the Public Facing Internet.

Best Practice - Keep Port 80 Open

Presently you have no ports open
