What Can I Do If the Connection Test Failed?

On the Instances page, click the instance name to go to the Basic Information page. In the Network Information area of the page, view the VPC where the instance is located.
Check whether the instance to which distributed transactions are added is in the same VPC as an ECS.
- If they are in the same VPC, see Why Does Communication Fail Between Two ECSs in the Same VPC or Packet Loss Occur When They Communicate?
- If they are in different VPCs:
  - Public access: Bind an EIP to the instance. For details, see Binding an EIP.
  - Private access: Create a VPC peering connection. For details, see VPC Peering Connection Overview.
  - Change the VPC hosting the ECS to the same as that hosting the GaussDB(for MySQL). For details, see Changing a VPC.
