Failed to obtain a certificate when setting up pterodactyl server on linux

My domain is:,

I ran this command:

bash <(curl -s

It produced this output: The process of obtaining a Let's Encrypt certificate failed!

My web server is (include version): HTTP, HTTPS

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

My hosting provider, if applicable, is: Oracle Cloud

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): I don't know.

That is not very much to work with. Was there a log or further details about the error?

I would only guess that you have the error shown by the Let's Debug test site


Just guessing here, but it might be an RSA / ECDSA issue.
