26.1 Access Gateway Throws a 403 Forbidden Page Error for a Resource Protected by a Form Fill Policy

This issue happens if a web server returns a form with a HTTP 403 error code. Access Gateway, by default, returns its own custom error pages. Hence, this prevents the Form Fill feature to work.

To workaround, perform the following steps:

  1. Click Devices > Access Gateways > Edit > Advanced Options.

  2. Specify ProxyErrorOverride off.

  3. Click OK.
