I found the solution . SAP System stops the agent Instance  every 30 minutes if you are not  using the license key .

The following should be in running mode

1. Management Host (Windows services )

2.Agent Instance ( See Log Tab if there is any issue  connecting Configured Alias/subscription  )

3. Matrikon server should be up
