Expiration date over 3 month

Hi! I have updated the certs I use and the validity is set for 3 month as intended:
Not Before: Apr 26 13:44:22 2023 GMT
Not After : Jul 25 13:44:21 2023 GMT

But when checking the certificates directly in the browser, the expiration is set for 1 year:
Validity Period
Issued On Wednesday, April 26, 2023 at 1:30:21 PM
Expires On Thursday, April 25, 2024 at 1:30:21 PM

Is there a known bug that does that?

I've followed instructions that my organization provide to update certificates so I'm not sure exactly what I've done and what information I can provide. We've searched for an explanation but we found nothing that look like our problem.

Probably a certificate from a different CA.

I've also moved your thread away from the #client-dev category into the #help category, as it does not seem to have anything to do with developing ACME clients.


And, had you posted in Help to start with you would have been shown this form.


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):


Issued by what Certificate Authority?


For Some reason I didn't look at the CA (NordVPN S.A.). I've check on an other device and the expiration is 3 month there.


Was "NordVPN S.A." the issuer? Because if so, that would be kinda weird IMO, as in, a Man-in-the-Middle-attack by your VPN software? Personally, I would not like that at all..


Me neither.. We're looking into that. Thanks a lot
