Hello, I have the following setup -> API Gateway -> (through VPC Link) NLB (internal facing) -> ALB (internal facing)-> ECS.
The NLB has a listener for the 443. It forwards to the ALB target groups for TCP 443.
When i tired https://"NLB domain":443 in api gateway, i got "Execution failed due to configuration error: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target" error. What am i missing here? The listener for ALB target group doesn't allow certificate.
Any help would be appreciated. Thank you!
Hello iwasa, Do you know how to configure on NLB? I don't see such option when i use the ALB target group. Thank you!
