Why is the Remote Control session not disconnecting immediately even when the session has ended?

Description

• This article provides details on what is causing the remote control icon to stay connected even when the connection has ended (icon not switching instantly from red to blue) or connection was lost.

Environment

• N-able N-central

Solution

N-able N-central creates the tunnel for the remote control session using the java webstart JNLP file that is executed. It does not close the tunnel until the session is completed or somebody/something kills the java webstart application. If a connection is timed out due to no usage or something along that line those are settings on the RDP server running on the system you are connecting to. Only timeout that we have is the 2 minute timeout when trying to start the tunnel connection.

As for the button going from red to blue, we try to detect when the java webstart has been closed and close the remote control session on N-able N-central to bring it back to blue but it is not something that can always be caught. Expected behaviour is for user to disconnect it if it's still showing. If they leave it alone there is a task on N-able N-central that runs to kill any non-active session (java webstart is not connected to N-able N-central anymore) and return it to "blue" which ideally is run about every 5 minutes.
