403.17

Client certificate has expired or is not yet...

 
  Description  
     
 

Some web sites require you have a special certificate to access the site. This typically occurs with higher security sites, such as a corporate web site for employee access only. It appears you have the certificate and it is invalid or it may not be enabled yet on the server.

 
 
   
  Example  
     
 
Windows
Server Error

403.17 - Forbidden: Client certificate has expired or is not yet valid.

Your client certificate has expired or is not yet valid. A Secure Sockets Layer (SSL) client certificate is used for identifying you as a valid user of the resource.

 
 
Error messages will differ depending on the web server and if replaced by the web site designers.

You will need to contact the web owners to get a new certificate (what is called a client SSL certificate) if your current certificate is invalid.

If you just got a new certificate, you may need to try again later if the certificate start date is later than the current date.
