The VPN connection is normal, indicating that the negotiation parameters at both ends of the VPN connection are correct. You need to perform the following operations:

Verify that routes to the VPN device in your on-premises data center are correctly configured.
Verify that inter-subnet data exchange is allowed on the VPN device.
Verify that NAT is not performed on the on-premises subnets that need to access the cloud.
Verify that mutual access between the public IP addresses of the VPN gateway and customer gateway is permitted.
