Issue Statement: Outside a VDI, a ServiceNow error message containing an IP address usually indicates that the IP address of the machine (home network, public Wi-Fi) is not whitelisted in the instance's IP Address Access Control list or is being blocked by a corporate firewall or proxy.
Concern: Security team raised the concern that exposing machine ip address in the error message - its a security concern.
e.g if you hit following URL
https://<your _servicenow_instance>.service-now.com/nav_to.do?uri=%2Fknowledge.do
The server returns a generic HTTP 403 (Access Restricted) message, which may expose internal system behavior and facilitate enumeration or exploitation.
Current status: An Idea (by my Client ServiceNow id) has been raised if it can be fixed.

That link fails in my instance, with: "
The page you are looking for could not be found."
