Only thing that comes to mind is that with Chrome, root certificates have to be installed separately in the browser as Chrome doesn’t use the OS’ certificate list. But even then, the error clearly states that the cert is revoked, not that it couldn’t be verified.
What certificate are you using on pfSense? You don’t happen to have one of those Lets Encrypt certs that were all revoked in stages beginning a few weeks back?
It is using a self-signed cert that expires in 2025. I noticed in the Pfsense update that it limits them to 825 days I think because longer expiration dates cause problems with some browsers. Hopefully, it will fix it after I upgrade.
