Hello.
Is Global Accelerator's endpoint type ALB?
In the case of ALB, as you know, if the health check of the target group is successful, then Global Accelerator should also be successful.
If the endpoint type is EC2, health checks are performed directly from Route53 to the EC2 IP address, so access from Route53 must be allowed in the security group's inbound rules.
You can check the IP that Route53 uses for health checks from the URL below.

Yes, the endpoint is an ALB. The health check of the target group is successful and shows the EC2 instance as healthy, however, the Global Accelerator shows the ALB endpoint as unhealthy. Are you saying I still need to allow ROUTE53_HEALTHCHECKS service IP address to my target group EC2 endpoint?
