Why Isn't the Data Source Connected to DataArts Insight Working?

The possible causes are as follows:

• Check if the VPC and subnet of the data source are connected.
• Check if the VPCEPndpoint Administrator policy is granted.
• Check if the security group of the peer data source allows access from DataArts Insight's CIDR blocks.
• Check if the VPC network has set ACL rules to restrict network access.
