Problems rate limit


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

My domain

I ran this command: + Signing domains…

It produced this output:

“type”: “urn:acme:error:rateLimited”,
“detail”: “Error creating new authz :: too many currently pending authorizations: see”,
“status”: 429

My web server is (include version): nginx

The operating system my web server runs on is (include version): Arch Linux

My hosting provider, if applicable, is: ELSERVER.SRL

I can login to a root shell on my machine (yes or no, or I don’t know): yes

I’m using a control panel to manage my site (no, or provide the name and version of the control panel): no


Please see this article:

I suggest that you:

  • Apply for a rate limit exemption from Let’s Encrypt.
  • Submit the domain to the Public Suffix List , which is used by Let’s Encrypt, but also has broader implications for things like HTTP cookies in web browsers. (For example, wouldn’t be able to set a * cookie and hack .)

It seems that you have too many currently pending authorizations.



Hi @eliseo

What ACME client are you using? Does it have any more detailed logs? Usually hitting the pending authorizations rate limit indicates that there’s a bug or misconfiguration with your ACME client resulting in it creating many authorizations but never attempting to fulfill them.


I appreciate you trying to help @2e0eej but I don’t think this is the correct advice for this situation. The pending authorizations rate limit won’t be affected by changes to the Public Suffix List and a rate limit adjustment for pending authorizations is usually only appropriate for very large hosting providers with a great deal of concurrent certificate issuance.
