Scenario: When remote users attempt to log on through NetScaler Gateway, they are presented with the following error message: `Cannot Complete your Request.' When the same users are in the office…

StoreFront uses the Callback URL to communicate back to NetScaler Gateway to validate session tickets issued by the Secure Ticket Authority. When remote users connect via an external URL but the Callback URL in the StoreFront Gateway configuration points to an internal or incorrect address, StoreFront cannot reach the Gateway to complete the request validation, producing this specific error. Setting the Callback URL to the external NetScaler Gateway URL ensures StoreFront can successfully reach it from the perspective of the external network path.

Pass-through authentication is a credential delegation method that affects how user credentials are forwarded; it does not resolve URL routing or session ticket validation failures.

The StoreFront URL in the Gateway configuration is the internal address the Gateway uses to reach StoreFront - changing it to the external URL would break Gateway-to-StoreFront communication on the internal network path.

External Beacon addresses are used by Citrix Receiver to determine whether a user is on the internal or external network to select the appropriate Gateway; they do not affect session request completion once a path is selected.
