[Newbie] Issues with too many requests for single domain


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: dtn.plosz.ca

I ran this command: Using zerossl.com

It produced this output: Too many certificates issued for domain

My web server is (include version): Apache 2

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

My hosting provider, if applicable, is: Media Temple

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

I am new to generating SSL certificates through Let’s Encrypt and I have accidentally generated too many using Zero SSL because of CSR issues I had with the host. Mostly my lack of experience going this route. How do I go about having these unused SSL certificates for the domain purged? Cheers.


No such thing! The basis of the rate limit is that you’ve already expended the resources required for Let’s Encrypt to create the certificate, deleting them isn’t going to un-spend those resources.

You can evade this particular rate limit by creating a new certificate that has a second name on it.

For example, the certificate you created has just one name:

  1. dtn.plosz.ca

You can’t create one like that anymore for another few days, due to the Duplicate Certificate Limit. But you could create a certiifcate that had a different set of names, as it would no longer count as a duplicate:

  1. dtn.plosz.ca
  2. www.dtn.plosz.ca
