## Symptoms

- * When the user tries to add an RDP application from Harmony Connect \> Policy \> Trusted Application, the operation fails with an error.

* Error: "Oh snap! We have encountered a failure while processing your request".

## Cause

If you add a new RDP application using the IP address range from 172.17.0.0/16, Check Point blocks the use of this subnet range, as it is the Docker default bridge network and could cause   
traffic problems to the connector.

## Solution

Define the RDP application with an FQDN instead of the IP address.
