i am trying to access my electronic training jacket on Navy Knowledge Online to check the status of my security clearance. the ETJ page requires an SSL certificate. when i initially loaded the page the message window popped up prompting me to add the security exception and get the certificate. i got the certificate and continued to load the page but it came up with HTTP error 403.7 saying that i didn't have the certificate i needed. for some reason NKO isn't recognizing the certificate i got so i need to clear that certificate and get a new one that hopefully the server will recognize. how can i do this?
