B ECS instances in different VPCs cannot communicate with each other. To achieve communication between two ECS instances in different VPCs, use Express Connect, VPN Gateway, or CEN to connect them. When doing so, make sure the security group rules allow access between the target ECS instances. https://www.alibabacloud.com/blog/ecs-security-groups-configuring-guide_595115
