Can you remove Rate Limit for my IPs

Hi there,
I am running a few cluster for the domains *

Since we configured the server incorrectly, after reinstalling it was rate limtited IP. Can you please remove the rate limit?

List of Rate-Limited IPs: (

Again, apologies from our side for hammering your servers, this has been addressed on our side.

Thank you!

Just to make sure, which rate limit, or rate limits, have you encountered? What were the error messages from Let’s Encrypt?

Was it the one about “ridiculously excessive traffic”? The other rate limits go away automatically over time.


Hi @sufalo

I can confirm that this IP address is not one that we have blocked administratively for sending excessive traffic.

Can you answer @mnordhoff's questions (thanks!) about the exact error you're receiving?

Hi @sufalo

you have created 5 certificates in the last days:

That hits the limit.

Isn't it possible to use one of these? If not, you have to wait a few days (~~ 2019-03-07) to create the next certificate.

Or create one certificate with one domain name.

Your last certificate has two domain names:

But then you need two certificates.


To clarify this, there are several different kinds of rate limits. Most of them expire automatically (and can’t be changed by Let’s Encrypt staff). However, one special rate limit (called “ridiculously excessive traffic”) does not expire automatically and requires intervention by Let’s Encrypt staff, which must be requested on the forum.

It can be confusing because people sometimes ask about both kinds on the forum, which might lead to the impression that all rate limits need a request here. But if the rate limit in question is any kind other than “ridiculously excessive traffic”, it’s not useful to request a response here because the staff can’t change the other limits.

It seems from @JuergenAuer’s and @cpu’s responses that the limit is not one that the staff can change, but is one that resets out automatically within a week.


Hi all,
Thanks @cpu, @JuergenAuer for helping me answer my questions.
Thank you very much!

Hi @schoen ,
I understood my problem.
Thank you very much.

hi @JuergenAuer,
Today is March 7, 2019, but I have not yet created an SSL certificate for my domain:
How can I install it when I give an error message?

Looks like you didn't read the list:

Your oldest certificate:

2019-03-01 03:06:57 UTC

Add 7 * 24 hours.

My problem has been solved.
Thanks for providing the information that helped me understand the problem.

Thanks all.
