The following error code is returned by the Citrix Gateway to CWA app when application/desktop launch fails:
Failed to launch session <session_name>. Error code: 2524

This error indicates failure to establish connection with VDA (Virtual Delivery Agent) IP address from Citrix Gateway. To resolve this issue, verify if VDA is reachable to Citrix Gateway. 
Note: This applies to VDA's that are available and showing as 'registered' in Citrix Studio. 

To verify the reachability from the Gateway, create a service to the VDA on ports 1494/ 2598 on the Gateway:
Example:
> add service vda1 192.168.1.1 TCP 2598
> add service vda2 192.168.1.1 TCP 1494

If this service is marked as UP, there is no issue with the reachability
(To check the service state from the CLI, use the command: "show service <service name>". Example: "show service vda1")
