What Can I Do If the Connection Test Failed?
Fault Locating
- Check security group rules.
- Check network ACLs.
- Check the NIC information of ECSs.
- Check the disconnected ports.
Solution
- Log in to the management console.
- Click
in the upper left corner and select a region and a project. - Click
in the upper left corner of the page, choose . - 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.
- Change the VPC hosting the ECS to the same as that hosting the GaussDB(for MySQL). For details, see Changing a VPC.
