Load balancer doesn't show/reflect the resource map.

I apologize that you're experiencing issues with the load balancer resource map not loading. Based on the information provided, here are a few potential reasons and suggestions to troubleshoot the issue:

1. Recent feature introduction: The resource map for load balancers is a relatively new feature. It was introduced for Application Load Balancers (ALB) in March 2024 and for Network Load Balancers (NLB) in April 2024. If you're using an older load balancer type or if your AWS console hasn't been updated, this could explain why the resource map isn't loading.

2. Load balancer configuration: There might be an issue with the load balancer configuration itself. Ensure that your load balancer is properly set up and associated with your Auto Scaling group.

3. Deleted resources: If the specified load balancer or any of its associated resources (like target groups) have been deleted, it could cause issues with the resource map loading.

4. Console or browser issues: While you've mentioned trying different browsers and devices, persistent console issues can sometimes occur.

To troubleshoot:

1. Verify that you're using either an Application Load Balancer or a Network Load Balancer, as these are the types that support the resource map feature.

2. Check if the load balancer and its associated resources (listeners, target groups, etc.) are still present and correctly configured.

3. Try creating a new load balancer and Auto Scaling group to see if the issue persists with a fresh configuration.

4. Clear your browser cache and cookies, or try using an incognito/private browsing window.

5. Contact AWS support if the issue continues, as there might be a problem on the AWS side that needs to be addressed.

Remember, the resource map is designed to provide a visual representation of your load balancer's architecture, including relationships between listeners, rules (for ALB), target groups, and targets. If it's not loading, you may need to rely on the individual configuration tabs for now to manage and troubleshoot your load balancer setup.
