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](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: [awesomewebapps.com](http://awesomewebapps.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? * * * 1: [awesomewebapps.com](http://awesomewebapps.com) 2: [www.awesomewebapps.com](http://www.awesomewebapps.com) * * * Select the appropriate numbers separated by commas and/or spaces, or leave input blank to select all options shown (Enter 'c' to cancel): 1 Requesting a certificate for [awesomewebapps.com](http://awesomewebapps.com) Certbot failed to authenticate some domains (authenticator: apache).
