Cannot obtain a certificate

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. |, so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.

My domain is:

I ran this command:

sudo certbot certonly --standalone

It produced this output:

Certbot failed to authenticate some domains (authenticator: standalone). The Certificate Authority reported these problems:
Type: unauthorized
Detail: Invalid response from []: "<!doctype html><html lang="en"><meta http-equiv="content-type" content="text/html;charset=utf-8"><meta name="viewport" con"

Hint: The Certificate Authority failed to download the challenge files from the temporary standalone webserver started by Certbot on port 80. Ensure that the listed domains point to this machine and that it can accept inbound connections from the internet.

Some challenges have failed.
Ask for help or search for solutions at See the logfile /opt/homebrew/etc/certbot/logs/letsencrypt.log or re-run Certbot with -v for more details.

Welcome to the Let's Encrypt Community :slightly_smiling_face:

Since is currently parked with GoDaddy, it does not currently have a host server upon which to run a website. In order to use the standalone authenticator, you need to run certbot on the server that actually hosts the domain name, not your home laptop (unless that is the hosting server, but I highly doubt it). Even if you managed to acquire a certificate using the manual DNS authenticator, you would have nowhere to install it at present.
