Global Accelerator endpoint group issues.

AWS Global Accelerator is a service that allows you to improve the availability and performance of applications by using static IP addresses (Anycast) and a global network infrastructure. If you're experiencing issues with your Global Accelerator endpoint group, here are some steps to troubleshoot the problem:

1. Check Global Accelerator Status:
   • Verify the status of your Global Accelerator using the AWS Management Console. Look for any alerts or warnings that might indicate issues.
2. Review Endpoint Group Configuration:
   • Double-check the configuration settings for your Global Accelerator endpoint group. Ensure that all settings, including the list of endpoints and their health status, are correctly configured.
3. Verify Health of Endpoints:
   • Ensure that the endpoints associated with your endpoint group are healthy and responsive. Check the health status of each endpoint in the AWS Management Console.
4. Check Network Configuration:
   • Ensure that there are no issues with the network configuration of your endpoint group, including security groups, route tables, and VPC settings.
5. Monitor CloudWatch Metrics:
   • Use CloudWatch to monitor metrics for your Global Accelerator. Look for any unusual activity, such as high utilization or error rates.
6. Verify Endpoint Health Checks:
   • If you've configured health checks for your endpoints, ensure that they are correctly configured and that the endpoints are passing the health checks.
7. Review Listener Configuration:
   • Check the listener settings for your Global Accelerator. Ensure that the correct protocol and port are specified.
8. Check Health Check Intervals:
   • Verify that the health check intervals are set appropriately. Too frequent health checks may lead to false positives, while too infrequent checks may result in delayed detection of issues.
9. Check for Resource Limits:

12. AWS CLI and SDK Versions:
    • Ensure you're using the latest version of the AWS CLI and SDKs, as older versions may have compatibility issues.
13. Review AWS Documentation:
    • Consult the official AWS Global Accelerator documentation for specific troubleshooting steps and best practices.
14. Contact AWS Support:
    • If the issue persists and you're unable to resolve it, consider reaching out to AWS Support for further assistance.
