VESTACP and Cloudflare -> Error: Let's Encrypt new auth status 429, rate limit, WHY?

Hi evreyone! Another rate limit in VESTACP here.

But I can’t find the problem, sorry. I have been actively searching for it aroung 1 week ago, and now I am desperate.

My domain is:

I ran this command: Add a new domain to VESTACP as usual, and never gets a SSL certificate.

It produced this output:
Error: Let’s Encrypt new auth status 429

My web server is (include version):
vesta 0.9.8
Ubuntu 18.04 (64 Bit)

I use CloudFlare as DNS.

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

I have already seen these websites, but I can’t still find why I got to the rate limit:

Any help is really appreciated!!


Hi @lesudo

you have all you need. Read the output of

Issuer not before not after Domain names LE-Duplicate next LE
CloudFlare Inc ECC CA-2 2020-04-08 2020-10-09 *,, - 3 entries
Let’s Encrypt Authority X3 2020-03-24 2020-06-22 - 1 entries

There is a certificate.

And it looks that you use it, because Cloudflare is able to connect your domain.

I don’t know what VestaCP is doing if you have a valid certificate.

Wait one hour, then the failed validation limit should be gone.

Then try it one time and see, if you can find a better log with the reason.

looks ok, that looks like a correct VestaCP answer.

Good: Acme-Check - Answer looks like a correct keyAuthorization - String: Filename + “.” + base64url(Thumbprint(accountKey)). So creating a Letsencrypt certificate using that integrated solution should work. Don’t use another client (like Certbot). Don’t mix integrated solutions with own ACME-clients, that may not work.

I solved it. Please delete this post, as I will publish a new post of how I did it but with no info of my client’s website.

Thanks @JuergenAuer


I already post the fix here:
