Unable to renew

Help

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), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.

My domain is: api.ali.actor

I ran this command: sudo certbot renew

It produced this output:

Odd. Does this work?

sudo certbot renew --cert-name api.ali.actor --preferred-challenges http

Could be the known bug about this error message in 0.31.0, but first try @_az's suggestion.

Does that require putting a file on a URL? I'm running a custom backend on this subdomain so would prefer not having to do anything that requires web server related stuff.

The standalone plugin, which you are already using, starts its own HTTP server temporarily in order to serve the challenge response.

I honestly had forgotten about the bug @Osiris is referring to (https://github.com/certbot/certbot/issues/5342 I think)? If you issued the certificate manually via DNS recently, that bug would be relevant, in which case my advice wouldn't help.

That bug would have introduced the error if that's the case? As the bug report was for 0.20.0 and was fixed in 0.31.0, the version @aliakhtar is using :stuck_out_tongue: But I remember it had something to do with reusing authz indeed.

All right - this worked. Is this the command I should run in future when updating?

No, you shouldn't need it next time. The /etc/letsencrypt/renewal/api.ali.actor.conf file should now have that extra parameter recorded, so it will be automatically applied at the next automatic renewal.

Good to know this wasn't the aformentioned bug. I guess that was indeed fixed in 0.31.0.
