Synology maximal certificate requests reached for this domain name

Is there a way to reset the certificate request?
I installed new diskdrives in my Synology NAS so I started from scrap. When requesting the certificate I get a message that the server can't be reached (I forget to setup the DDNS). After setting up the DDNS I got the message "maximal certificate requests reached for this domain name"

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. crt.sh | example.com), 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:

It produced this output:

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):

The version of my client is (e.g. output of certbot --version or certbot-auto --version if you're using Certbot):

Two things:

  • No, rate limits cannot be reset manually or by anything done by the user, such as revoking certs;
  • What exact limit are you hitting? If your DDNS wasn't set up correctly and you didn't get any certificate issued, you're most likely hitting a rate limit with a window of just an hour.. But we'd need the full error to see which rate limit you've hit.

Hello Osiris,

Thank you very much for your quick response and time!

It seems indeed that I ran into a rate limit with a time window. I tried today again to request a certificate via Synology and it's processed without any problems.

All rate limits have a time window, but some are just a few hours where others (more serious rate limits) have windows of 7 days. :slight_smile:
