WebGate Error Report - The URL /access/sso is reserved for use by Oracle...

Question

We are getting a 500 error on the web gates when logging in.
They have been working before, but are now reporting the error below.

thanks,
the login post goes to /access/sso, but now i am getting 404 error /access/sso
Below is what I currently have the following in httpd.conf, which is the same as in a working environment.
The web gate policy resources include /portal and /public, but no mention of /access. How does web gate know how to intercept /access/sso?
