Storefront-based Scout seems like running fine but ended up failing with the following reason -
Citrix Storefront-based Scouts with Custom Hive opens a WebSocket-based session to the tested published resource. Unfortunately the standard CAVD policies prohibit internal WebSocket connections by default, and this causes the Scout to fail to open the session.
To allow successful connection to the published resource from a Custom Hive the WebSockets connections policy need to be enabled.
Enabling WebSocket Connections on CAVD via Policies
- Go to the Group Policy Management Console or Citrix Studio to configure HDX policies.
- Select the WebSockets connections policy setting, and allow WebSockets connections.
- Assign to the relevant Delivery Group and Enable the policy.
