HI @Rashmi Mohanty ,
Have a look at this troubleshooting guide to ascertain what the issue might be. Specifically, the Debug access to virtual network-hosted resources section of the docs. You could be blocked for one of the following reasons:
- Your routes aren't configured with your subnet or point-to-site address ranges in your on-premises gateway.
- Your network security groups are blocking access for your point-to-site IP range.
- Your on-premises firewalls are blocking traffic from your point-to-site IP range.
- You're trying to reach a non-RFC 1918 address by using the regional virtual network integration feature.
