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. https://crt.sh/?q=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: cachedesk.com
It produced this output: Certbot failed to authenticate some domains (authenticator: nginx). The Certificate Authority reported these problems:
Detail: 2604:a880:400:d0::201e:5001: Invalid response from http://cachedesk.com/.well-known/acme-challenge/YT_no9YBrw_DYsoXNXC3_GDXY0LUDAHe6TK2TXgGpc4: 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.
My web server is (include version): nginx/1.18.0
The operating system my web server runs on is (include version): Ubuntu 22.04
My hosting provider, if applicable, is: digitalocean
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 1.21.0
I only have one IP and plan to run multiple sites, so I wrote my own script to batch create NGINX files and request certificates for them. This is bugging me because I have successfully changed DNS A records and AAAA records, but cannot apply for CA. i looked up similar issues in the forum within 48 hours, but none of them could be resolved. I really have a headache.
