Error Certificate signature failed

Hi Dear Lets Encrypt
My domain is:
I try 7 time to have a certificate for my web…but after some times it came a page
please help me because its important for me…I cant wait for 5 or 7 days

with this error:
It produced this output: Certificate signature failed. If you supplied your own CSR make sure the domains on it match what you put on SSLForFree. If there is a rate limiting error at the end of this paragraph certificates per Domain is currently 5 per 7 days. Try asking Lets Encrypt to increase the limit or wait 7 days. Rate limits should increase in the near future. { “type”: “urn:ietf:params:acme:error:rateLimited”, “detail”: “Error finalizing order :: too many certificates already issued for exact set of domains:, see”, “status”: 429 }

My web server is (include version):

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

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): cpanel

With respect

The rate limit is simple, but you need to edit the domain list in order to work around it…

What’s the domain set you are trying to obtain an certificate?
Thank you

my web is and I want to get certificate from

There are rate limits in place to protect Let’s Encrypt from too much load on their systems. See for more information. You’ve seem to hit the “Duplicate Certificate” rate limit, as you’ve got 5 certificates for the two FQDNs and in the past 7 days.

Is there a reason why you’re getting exactly the same certificate over and over again? You should try to save the certificate issued on sslforfree together with the private key on a place on your computer so you can find it again without needing to get a new certificate.

Hi @azizi

you have a lot of certificates created:;include_subdomains:false;

What's the problem to use one of them?

I too have the same issue dont know whats wrong but little help would be much be much appreciated.
