Too many certificates issued

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.

My domain is:

I ran this command:
certbot certonly --manual --preferred-challenges dns-01 -d -d -d -d --server
I have used this before to create valid certificates, however this error suggests that there are too many certificate requests or certs created, which seems not true. I tried over the course of multiple weeks to check if I really run into rate-limits.
I also tried to verify via, which doesn’t list any certificates for

It produced this output:
An unexpected error occurred:
There were too many requests of a given type :: Error finalizing order :: too many certificates already issued for: see

My web server is (include version):
using certonly

The operating system my web server runs on is (include version):
Debian 8

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


Hi @reinhard-brandstaedt,

The rate limit problem here is certificates for subdomains of

It looks like certificates for subdomains containing a new hash or key value are being created automatically with some frequency. Is there any way to do this less often, create them under a different domain, combine several of these into one certificate, or otherwise reduce the frequency of this process?

Hi @schoen,

thanks! I didn't know that one can query subdomains that way!
That makes a lot of sense, it seems that someone else in our organisation is messing with cert creation! I will track that down.
Thanks a lot!
