Reset rate limit

So by mistake I reached 5 certificates per FQDN per week limit.

How can I know when the limit will be reset?




“We use a sliding window, so if you issued 10 certificates on Monday and 10 more certificates on Friday, you’ll be able to issue again starting Monday.” from

Thanks for using Let’s Encrypt!

thanks for your reply @jple, but that not the limit I reached (20 in one week) but the other one (5 dupes in one week).

I reached it today, does it means I need to wait till next friday?

Yes, if you want to issue a certificate that’s a duplicate of the existing ones. If you add or remove a name (such as an additional subdomain), that rate limit won’t apply.
