Error creating new order too many certificates

Hi Let's Encrypt,

how are you?

This is the first time that I try to install a Let's Encrypt certificate.
I installed Xeams 8.4 mail server on my QNAP TS-251D and when I went to create the certificate I was having problems due to port 80 being used by another process.

I was able to fix the port 80 issue and have been trying multiple times to create a certificate for using http xeams challenge.
After submitting, Xeams was asking me to restart the service, but it was crashing every time and the certificate wasn't being installed. Therefore after many attempts I removed Xeams and its configuration and reconfigured from scratch.
Now I get this error every time. How long do I have to wait before I can submit successfully?

Unable to create a new order. Error creating new order :: too many certificates (5) already issued for this exact set of domains in the last 168 hours:, retry after 2023-01-22T22:28:24Z: see Duplicate Certificate Limit - Let's Encrypt

Thank you.

Best regards

Hi @ab6540183, you will have to wait 168 hours, which is 7 days.
Please use the Staging Environment - Let's Encrypt until you get your environment working correctly.


Unfortunately these limits are not well implemented.

For example free TLDs such as, are completely unusable with letsencrypt because of such limits.

Please open a new thread about specific, non-ontopic issues. Generic complaints about rate limits warrant their own thread methinks.


Those, um, aren't TLDs. The TLD for both of those is .to; and are both registered domains under the TLD of .to. And if both of those are used to give "free" subdomains to others, then they should both be listed on the public suffix list. But that's something that, AFAIK, only the registered domain owner can do.


If the bus seats only 100 people...
How can you say the bus is completely unusable?
[when there are 100 people sitting in the bus (all the time)]

A better statement is that the bus is always full (when, and where, you need it).


Here are a couple of Wikipedia articles you might want to read through.
