Issue with auto renew

Internal errors are usually due to some kind of hick-up at the Let's Encrypts systems. I'm not seeing any recent disturbance, so maybe you were just unlucky.

Could you try again and see if it works this time?

Also: is your server really having April 26 as the current date? Or are you showing us a very old log?


Hi Osiris,

So that is actually the only error that I found in my logs but our cert was set to expire in 5 days from now and it never auto renewed. When I went back into the logs that is the only error that I could find but the dates lined up since the cert only lasts for 90 days. Once I ran the command manually certbot renew I did not have any issues getting a new cert but if I don't run the command certbot will not renew on its own for some reason.

Depending on how you've installed certbot, there might or might not have been a cronjob or systemd timer installed. Usually, one would run certbot renew twice a day through such a cronjob or systemd timer.


@Osiris I plan to uninstall my current version of certbot 1.11.0 and update to the latest version and see if that helps.
