Why Is the Error Message "communication link failure" Displayed When I Use a Newly Activated Datasource Connection?
- Possible Causes
The network connectivity is abnormal. Check whether the security group is correctly selected and whether the VPC is correctly configured.
- Solution
Example: When you create an RDS datasource connection, the system displays the error message Communication link failure.
- Delete the original datasource connection and create a new one. When you create a new connection, ensure that the selected Security Group, VPC, Subnet, and Destination Address are the same as those in RDS.
Select a correct Service Type. In this example, select RDS.
- Check the configurations of VPC.
If the error message is still displayed after you create a new datasource connection according to Step 1, check the VPC configuration.
- Delete the original datasource connection and create a new one. When you create a new connection, ensure that the selected Security Group, VPC, Subnet, and Destination Address are the same as those in RDS.
