Certificate Error Type
Description
Expired
The current date falls outside of the range of validity for the certificate.
Mismatched hostname
The hostname in the certificate does not match the hostname the client was 
trying to access. 
Note
The Web Proxy can only perform hostname match when it is 
deployed in explicit forward mode. When it is deployed in 
transparent mode, it does not know the hostname of the destination 
server (it only knows the IP address), so it cannot compare it to the 
hostname in the server certificate.
Unrecognized root 
authority/issuer
Either the root authority or an intermediate certificate authority is 
unrecognized.
Invalid signing 
certificate
There was a problem with the signing certificate.
