Errors renewing certificates all of a sudden MIAB v67

Last night I got the following errors in emailed to my admin account:
Provisioning TLS certificates for fullmoonmanor.net, www.fullmoonmanor.net.
error: fullmoonmanor.net, www.fullmoonmanor.net:
Saving debug log to /var/log/letsencrypt/letsencrypt.log
An unexpected error occurred:
requests.exceptions.ConnectionError: (‘Connection aborted.’, ConnectionResetError(104, ‘Connection reset by peer’))
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.

the logs on the server showed:

Any ideas?

honestly I would consider upgrading from v67 to v68 and see if this is resolved by the upgrade.

curl -s https://mailinabox.email/setup.sh | sudo bash

What happens if you retry from the Admin interface?

The cert problem corrected itself last night. It may have been an intermittent connection issue at the time of trying to renew?

Let’s encrypt now tries to connect from diffrent servers around the world. Yours might have been unreachable. Also there is a timeout for multiple tries when you doing it manually.
