Can’t renew certificate NAS Asustor

My domain is:

I ran this command: Don't know the command as it's my asustor nas that try to renew the certificate.

It produced this output: Sorry output is in french;
Le nombre de certificats délivrés par Let's Encrypt pour votre nom de domaine a atteint sa limite. (Ref. 5019)

My web server is (include version): the one with my asustor nas

The operating system my web server runs on is (include version): Asustor NAS OS (Last version)

My hosting provider, if applicable, is:

The problem here seems to be a limit of certificate for a domain but I have only one and want to renew it. The cerfificate was created on may 2021 and now it is expired, normally renew is automatic with my nas.

Maybe (For sure :slight_smile: ) I'm doing a wrong thing.
Could you please help me ?

Not sure, but that error message seems to say you've hit a rate limit due to too many certificates issued for your domain name? However, I can see only one currently: |

Not sure why your NAS would react with that error message though..

That said, your domain name isn't reachable on port 80 from the world wide web nor on port 443. Unless your NAS is using the dns-01 challenge, it's probably using the http-01 challenge, which requires a world wide open port 80.

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

What is the FQDN the NAS is using?

In fact I have cut access to my webserver with a firewall, I use the certificate to access another service, but if needed I can activate access to 80 and 443 in order to renew the certificate.

Please read how Let's Encrypt works:

Unless the dns-01 challenge is used, either port 80 or 443 or both needs to be open.


What is the name in the current certificate?

I read the working process. But I don't understand exactly what I have to do to answer this process.
I tried to opn both 80 and 443 and activate a website on NAS, but I still have the same message when I try to renew certificate.
