Hello! I've been using certbot for a number of years for certificates on my academic department's web server, but it stopped working recently.
My domain is: webwork.piedmont.edu
I ran this command: sudo certbot
*It produced this output: *
Saving debug log to /var/log/letsencrypt/letsencrypt.log
Please enter the domain name(s) you would like on your certificate (comma and/or
space separated) (Enter 'c' to cancel): webwork.piedmont.edu
Requesting a certificate for webwork.piedmont.edu
Certbot failed to authenticate some domains (authenticator: apache). The Certificate Authority reported these problems:
Detail: 22.214.171.124: Fetching http://webwork.piedmont.edu/.well-known/acme-challenge/3ajF-3RmeDZRvX8-nnM_wP1nx11MsWFCNDlsLAzugQo: Timeout after connect (your server may be slow or overloaded)
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.
