Hi @adamshaffa ,

This error message might not provide detailed information, but it typically signals an issue with the setup of health checks for your load balancer. Health checks are responsible for evaluating the condition and accessibility of your backend instances, and when they encounter problems, it can disrupt the load balancer's ability to distribute traffic efficiently.

Please check the following:

1. Confirm that your backend instances are in a healthy and responsive state. You can do this by directly checking the instances themselves and confirming that the services are running as expected.

2. Inspect the health check configuration linked to your load balancer. Confirm that the path and port specified in the health check match the settings of your backend instances.

3. Confirm that you have not exceeded any quotas associated with load balancers or health checks in your GCP project.
