I am trying to renew certs for this server, which are now expired. I've never run into this issue manually renewing before (but was never able to get it to auto-renew). Any assistance is greatly appreciated!
My domain is: chemanet.org
I ran this command: sudo /usr/bin/certbot --apache -d chemanet.org
It produced this output:
Saving debug log to /var/log/letsencrypt/letsencrypt.log
Renewing an existing certificate for chemanet.org
Certbot failed to authenticate some domains (authenticator: apache). The Certificate Authority reported these problems:
** Domain: chemanet.org**
** Type: connection**
** Detail: 18.104.22.168: Fetching http://chemanet.org/.well-known/acme-challenge/oB4Wvp5Ftiyd4GjRGPwrZjeoMUegp3VzkuBEHl75Huw: Connection reset by peer**
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.
