Maximal certificate requests reached for this domain name

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.

Hello @Chad17, welcome to the Let's Encrypt community. :slightly_smiling_face:

As Let's Debug shows you have hit the Rate Limits results here

So please wait; or use one of the already issued certificates |
or here

Testing and debugging are best done using the Staging Environment as the Rate Limits are much higher.

And to assist with debugging there is a great place to start is Let's Debug.

Also here is a search of the forum for Synology Search results for 'Synology order:latest' - Let's Encrypt Community Support

This is a lot of issued certificates, really!

I don’t have the certificate downloaded so I cannot reuse those; there’s no way to remove the restriction for one attempt? Do I need to wait a week before I can attempt to create one again?

You threw away five perfectly good certs today :frowning:

Sadly, yes.


Do you still have the associated PRIVATE KEY(s)?

You can download an already issued certificate, for example here | 8780730950
Find the Download Certificate: PEM

Well it’s not that I “threw them away” I went to reapply it once and it generated that message. Not sure when it attempted 5 times. Also it was through the security —> certificates area so I wasn’t downloading them they were applying directly to the NAS.

Oh well though, good to know I’ll wait the week.

Thank you for the quick responses

If you can SSH into the NAS, try looking for the cert files and any log files that might better explain the (actual) problem.
The problem isn't going to fix itself simply by waiting one week.
It failed (at least) five times in a row...
It will likely fail on the sixth one too [unless the problem is found and corrected].
