The certificate authority failed to verify the temporary nginx configuration changes. Ensure the listed domains point to this nginx server and that it is accessible from the internet

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: teamgames.store

I ran this command: sudo certbot --nginx -d teamgames.store -d www.teamgames.store

It produced this output:

Saving debug log to /var/log/letsencrypt/letsencrypt.log
Requesting a certificate for teamgames.store and www.teamgames.store

Certbot failed to authenticate some domains (authenticator: nginx). The Certificate Authority reported these problems:
  Domain: teamgames.store
  Type:   dns
  Detail: no valid A records found for teamgames.store; no valid AAAA records found for teamgames.store

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

My web server is (include version): nginx 1.24.0

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

My hosting provider, if applicable, is: Digital ocean

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): digital ocean / terminal

The version of my client is (e.g. output of certbot --version or certbot-auto --version if you're using Certbot): 2.1.0

I am able to access the website via visiting the domain www.teamgames.store. It's showing the Godot message that I expect it to show at the moment.

root@galaxy-game-server:/etc/nginx/sites-enabled# curl -4 ifconfig.co

matches my A

Hi @wadlo, and welcome to the LE community forum

@wadlo

Detail: no valid A records found for teamgames.store;

I suppose that was a temporary error.
I'd try it again.
But you should be doing these types of tests [yes, this is now testing] on the staging environment.

sudo certbot --nginx -d teamgames.store --dry-run
sudo certbot --nginx -d www.teamgames.store --dry-run

See if they both pass individually.

Figured out I need both a www hostname and a @. For those looking at this in the future.

So, you had no A record for LE to find - LOL

Also:

@wadlo

Certbot): 2.1.0

That could do with an update.
