Certbot failed to authenticate some domains

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. https://crt.sh/?q=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: apiedup,myvnc.com

I ran this command: sudo certbot --apache

It produced this output: Saving debug log to /var/log/letsencrypt/letsencrypt.log

Which names would you like to activate HTTPS for?
We recommend selecting either all domains, or all domains in a VirtualHost/server block.

1: apiedup.myvnc.com

Select the appropriate numbers separated by commas and/or spaces, or leave input

Certbot failed to authenticate some domains (authenticator: apache). The Certificate Authority reported these problems:
Domain: apiedup.myvnc.com
Type: connection
Detail: 197.188.132.210: Fetching http://apiedup.myvnc.com/servererror.php?code=401: Redirect loop detected

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.

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.

Your 'website' (not sure what it should run or show) as per the error message indeed has a redirect loop. It never shows the actual page that should be showed.

See e.g. redirect checking websites like Redirect Checker | Check your Statuscode 301 vs 302 for what your webserver does.

Please fix your redirect loop and try again.
