Set up .app auto Certbot Failed

Hi i am trying to install Certbot with the auto certificate update cause I am noob when it comes to this. I Think my issue is I don't have a valid HTTP address because .app requires HTTPS to navigate to. I know my public IP address if I can insert that somewhere, but I'm a bit lost on that.

Thanks for the help.

My domain is:

I ran this command:

sudo certbot --nginx

It produced this output:

Certbot failed to authenticate some domains (authenticator: nginx). The Certificate Authority reported these problems:
Type: unauthorized
Detail: Invalid response from is coming soon "\n\n\n\n<meta content='3CbaVvw-I7Mlrmm"

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-common (1.24.0-1ubuntu1)

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

Ubuntu 23.10 x64

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):


I'm using a control panel to manage my site (no, or provide the name and version of the control panel):


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

certbot 2.7.4

Is this IPv4 the right one for your server? Or does it belong to someone else?


It is someone else.

You should replace it with your server's, in your DNS control panel.


I was able to find the IP address it was referencing, it was the DNS record on the site I purchased my domain from ( By updating that IP address to the ipv4 address of my digital ocean droplet, I was able to successfully run the certbot setup and install.

Thank you for your help @9peppe
