Maximum rate of 20/Week exceeded

HI, i had to reinstall my domain a few times because of issues with a wordpress theme. Every time I had to reinstall the certificate. Now I have a exceeded my rate of 20/week limit and I have a website which needs launching.

  1. do I need to wait 7 days or is there a way to reset it earlier
  2. If i try to install it every day until the rate is below 20 does this count as well as an installed certificate

My domain is:

I ran this command:
via plesk install let’s encryps ssl/tsl certificate

It produced this output:
Invalid response from
Type: urn:acme:error:rateLimited
Status: 429
Detail: Error creating new cert :: too many certificates already issued for exact set of domains: see

My web server is (include version):

CPU Intel® Xeon® CPU E5-2640 v4 @ 2.40GHz (2 core(s))
Version Plesk Onyx v17.5.3_build1705170317.16 os_CentOS 7
OS CentOS Linux 7.4.1708 (Core)

My hosting provider, if applicable, is:

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

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

There is no way to reset the limit earlier. But it will be seven days from the time the first certificate was issued.

No, the limit is on issued certs. A cert won't be issued if you're beyond the rate limits, so the counter won't go up with unsuccessful attempts.

Hi @xofnot,

Regarding this:

No, you have not reached this limit, you have reached this limit:

We also have a Duplicate Certificate limit of 5 certificates per week. A certificate is considered a duplicate of an earlier certificate if they contain the exact same set of hostnames, ignoring capitalization and ordering of hostnames. For instance, if you requested a certificate for the names [,], you could request four more certificates for [,] during the week. If you changed the set of names by adding [], you would be able to request additional certificates.

So if you add a new domain to your certificate... and for example you will be able to issue a new cert covering both domains.

Also, you have issued 5 valid certificates, next time you should backup some of them :P.

Thank you both for explaining.

never thought about backing up the certificate before reinstalling the domain. now I understand more. I’ll have to wait a few days more…

tx & have a nice day.
