Net::err_cert_date_invalid

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: iemmeconsulting.it

I ran this command: http://www.iemmeconsulting.it/

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):

Yes, the cert shown has expired.
But that is no longer the cert being served by your site:

So it would seem that you have corrected the problem.
Most likely the web service needed to restart/reload after the cert was renewed.
If so, you need to check your configuration - to include a deploy hook that can restart it for you automatically.
