This site (https://ssptrades.com) is currently giving me SSL problems... but only PC Firefox.
I can tell the certificate is TSL 1.2 by looking at it in another browser...would that be a problem? If it is how can I generate a certifcate or certificate request for TLS 1.3 using IIS?
This is the error on pc firefox 81.0.2 (64 bit)
An error occurred during a connection to ssptrades.com. Peer’s Certificate has been revoked.
Error code: SEC_ERROR_REVOKED_CERTIFICATE
