I have about 30 websites divided between two Hestia servers. They all have Let’s Encrypt Certficates and the DNS for all of them was set up properly with CAA records pointing to Lets Encrypt. I used Hestia to install the LE Certficates right after I added each website to its own user. Up until a few minutes ago, all were displaying well.
However, suddenly, none of my websites will display. They all have browser warnings claiming the certificates are not valid. Clicking accept risk takes me to this page (note that I am not using the FORTINET firewall):
FORTINET Webfilter… This Connection is Invalid. SSL certificate expired. A secure connection to createyourownonlinestore.org cannot be established. When you try to connect securely, sites will present trusted identification to prove that you are going to the right place. However, this site’s identity can’t be verified.
Certificate CN createyourownonlinestore.org
Certificate Authority R3

Note: I tried replacing the Lets Encrypt Certificate with a new one but I got the same error. Any help or ideas would be greatly appreciated.
Here are some claimed solutions I found on the Internet but I have not been able to implement any of them:
To fix the problem, we had to change the policy to a new SSL/SSH policy we created with no inspection of any ports. Once we applied that, the issue went away.
You need to enable “allow invalid cert” (set invalid-Server-cert allow) as a workaround.
