Hello @RustavDhara ,
I would be concerned if the machine could not ping to itself on localhost/127.0.0.1
I think you need to reach out for infrastructure support from your Azure provider, and ask them to find out the issue in the firewalls and VLAN configurations.
As indicated earlier, this issue is non SAS related. It is normal that you are confused and we can help little from here.
Kind regards,
Juan
