NET::ERR_CERT_INVALID

It’s crazy how internet explorer is the only one that works . I hate that browser.

@dono4312,
Thanks for reaching out to us.
You’re seeing this error because the sites certificate is unsecure is not guaranteed to be trustworthy. I know it seems silly, but are you 100% certain this is the correct address to the site you’re trying to visit?

When I try, I get the same results in pretty much every browser including MS Edge.

Yes, I’m sure of the address. Even on DOD Intranet machines this error shows up, but in FF and IE you can bypass it.

I use a Common Access Card/PIV to gain access to the site.

Hmm, interesting. Can you try visiting the site again, opening the Shields panel and toggling the Connections upgraded to HTTPS option “off” ? The page will refresh automatically and attempt to load again.

### The certificate is not trusted in all web browsers. You may need to install an Intermediate/chain certificate to link it to a trusted root certificate.

This server side issue. If IE accepts it, its because other browsers are more secure here. I tested Brave, Edge and Firefox, all failed to load this site.

one must use a PIN and CHIP ID Card to access the site

Understandable @dono4312 but the ssl cert isn’t correct, which is why its failing. Older browsers like IE will work for older certs, but anything newer will fail. I would recommend contacting the admins of this site to improve the SSL certs, it’ll make it more compatible with all browsers and more importantly make it more secure.
