Symptoms

Traffic cannot pass through a tunnel after the Edge client is switched to DTLS from TLS.

Impact

Traffic does pass through the tunnel. The Edge client hangs, and the status changes to 'Waiting to connect' 'Downloading server settings'

Conditions

Edge client switched to DTLS from TLS.

Workaround

None

Fix Information

Now, the Edge client correctly does not close the session locally if the server is not reachable because the session timeout check require fails.
