The domain name you are using has reached the maximum

I had a working Lets Encrypt certificate on a QNAP nas. Upon receipt of the certificate, the message "The domain name you are using has reached the maximum number of Lets Encrypt certificates" is issued
How do I get a certificate for nas QNAP?
I understand you need to wait for a timeout?

My domain is:jew.myqnapcloud.com
It produced this output: "The domain name you are using has reached the maximum number of Lets Encrypt certificates"

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

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

Hi @Serg, and welcome to the LE community forum :slight_smile:

According to the rate limits: Rate Limits - Let's Encrypt (letsencrypt.org)
The main limit is Certificates per Registered Domain (50 per week).

That means only the first 50 requests get approved per week.
There is no telling how many people try to register "myqnapcloud.com" names on any given week, so, there is no way to know your odds of success.

Note: Once a cert has been issued, their regular renewals are no longer rate limited that way.
So, you only need to get "lucky" once.

My advice to you is [choose one]:

  • switch to using another domain name
  • increase your attempt rate [note: rate limits are set at five per hour - so don't try to exceed that]
  • speak with QNAP about this problem - based on their use, they should easily be able to add that domain to the PSL
