Can't complete /usr/bin/certbot certonly --dry-run -v -d

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:

I ran this command:
/usr/bin/certbot certonly --dry-run -v -d www.ingber.com,ingber.com

It produced this output:

Certbot failed to authenticate some domains (authenticator: apache). The Certificate Authority reported these problems:
Domain: ingber.com
Type: unauthorized
Detail: 2600:3c01::f03c:91ff:fe93:e6f3: Invalid response from http://ingber.com/.well-known/acme-challenge/RMMykyhhgGXjJUJ_a0MC2_Sfeo51LlNyXbF9fEYgdFI: 403

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.
