HTTP-01 error at renewed nginx

The certificate is not renewed, I have no record of any changes being made on the server.

Port 80 are open in server and in firewall.

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:comnetsa.com

I ran this command: certbot renew --dry-run -v

It produced this output:

My web server is (include version): nginx version: nginx/1.18.0 (Ubuntu)

The operating system my web server runs on is (include version): Ubuntu 20.04.4 LTS

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): certbot 2.10.0

It looks like you have geo-blocking that is preventing the secondary validation from succeeding .
