Certificate Expiry

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. https://crt.sh/?q=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: chuo.fm

I ran this command:

It produced this output:

My web server is (include version): nginx

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

My hosting provider, if applicable, is:

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

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 just renewed my certificates last week, but i still got an email from LetsEncrypt, a reminder saying that my certificates are expiring in 10 days. Should I ignore the email because i think my certificates are renewed. Please let me know!

Hi @webmasterchuo

please read

When You Get an Expiration Email

If your certificate is already renewed, we won’t send an expiry notice. We consider a certificate to be renewed if there is a newer certificate with the exact same set of names, regardless of which account created it. If you’ve issued a new certificate that adds or removes a name relative to your old certificate, you will get expiration email about your old certificate. If you check the certificate currently running on your website, and it shows the correct date, no further action is needed.

Your old certificate has 4 domain names. You didn’t renew that certificate, instead, you’ve created a new certificate with 5 domain names.

So the old certificate isn’t renewed -> that’s the mail.


Even if the old certificate expire, and i have a new certificate up and running, my website wont run into any problem would it ?

Correct, if your web server is using the new certificate everything is fine. Your old certificate will expire and you might get a few more expiry emails but it won’t cause problems for users of your site.
