Port block scenario fails when run with ssm

[pandian912]

Describe the bug

ssm servers are blocked when performing network failure scenarios, hence the scenario fails

To Reproduce

Run a network failure scenario which blocks ssm messaging

Expected behavior

SSM has to be bypassed from the failure as failing the communication channel breaks the test.
