Issue with nginx & active24

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 | ucimesejs.cz), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.

My domain is: ucimesejs.cz

I ran this command: sudo certbot --nginx -d ucimesejs.cz -d www.ucimesejs.cz

It produced this output: Domain: ucimesejs.cz
Type: unauthorized
Detail: 2a00:4b40:aaaa:2005::7: Invalid response from http://ucimesejs.cz/.well-known/acme-challenge/NUpgurZFeimV5c0vjG5ssG25InT7-CevqhjJ3CP1_no: 404

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.

Some challenges have failed.

My web server is (include version):

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

My hosting provider, if applicable, is: dedicated server

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 --version

Does your site work via IPv6?

the ipv6 was configured from Active24... I noticed it only now, I removed the AAAA records and now I'm waiting until I can do another validation. because I exceeded the limit.,
