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: mlpronto.org
I ran this command: certbot -v --apache
It produced this output:
Requesting a certificate for mlpronto.org
Performing the following challenges:
http-01 challenge for mlpronto.org
Waiting for verification...
Challenge failed for domain mlpronto.org
http-01 challenge for mlpronto.org
Certbot failed to authenticate some domains (authenticator: apache). The Certificate Authority reported these problems:
Domain: mlpronto.org
Type: unauthorized
Detail: 2001:4860:4802:34::15: Invalid response from https://cs.wellesley.edu/~btjaden/MLpronto//.well-known/acme-challenge/q3qXOMose0i8hQl2-UmGvWjXHo6y29Sob6vLsMCcGRQ: 404
Hint: The Certificate Authority failed to verify the temporary Apache configuration changes made by Certbot. Ensure that the listed domains point to this Apache server and that it is accessible from the internet.
Cleaning up challenges
Some challenges have failed.
Ask for help or search for solutions at https://community.letsencrypt.org. See the logfile /var/log/letsencrypt/letsencrypt.log or re-run Certbot with -v for more details.

BTW, my reading of your help messages suggests that firewalls are often an issue, but I checked and this server is visible outside the firewall, both to a web browser and to curl:
curl --head http://mlpronto.org/

The logs show a 404 for the challenge:
