Unable to call the backend service

Last Updated: Dec 01, 2017

Check whether the entered backend service address is correct and make sure that the backend service can be accessed normally. If your backend service is on ECS, check the security group settings to see if it can be accessed externally. Make sure that the security group allows access to the IP section of the API gateway.
