Certificate expires

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: clausg.synology.me

I ran this command: I have no idea what to do

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):

I have no idea, what to answer. I just got the mail, but no information in the mail, how to renew the certifacate.

We recommend renewing certificates automatically when they have a third of their total lifetime left. For Let's Encrypt's current 90-day certificates, that means renewing 30 days before expiration. See Integration Guide - Let's Encrypt - Free SSL/TLS Certificates for details.

What ever I read, it did not help me. Thanks for recommendations.

Hi @Claus

you have created the older certificate.

So do that again.

But: Normally, Synology should renew certificates without interaction.

If that doesn't work? Oh - the answer is simple. Your domain port 80 doesn't answer.

Please read some basics:


A working port 80 is required to use http validation. Looks you have closed your domain, so the result (renew doesn't work) is expected.

Thanks for the help. port 80 was the hint.
