Certbot Error getting validation data

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: link.tgrust.xyz

I ran this command: certbot certonly -d link.tgrust.xyz

It produced this output: 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 (Ubuntu)

The operating system my web server runs on is (include version): Ubuntu 22.04 LTS (jammy)

My hosting provider, if applicable, is: Oracle

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): 1.21.0

I also cannot connect to your site. It looks like port 80 and port 443 are both blocked by a firewall or similar.

You must have a working http site to get a cert using the http challenge

The letsdebug.net is often helpful to test changes to see if your server is open to the public internet on port 80


Hi @TatumGG, and welcome to the LE community forum :slight_smile:

From that server, please show the output of:
curl ifconfig.co
nginx -T


Good tips but looks like they sorted it out
