Troubleshooting Guide for Utho Cloud TargetGroup

Common Issues

1. TargetGroup Not Distributing Traffic

Problem: The TargetGroup is not distributing traffic to the endpoints.

Solution:

• Server Health: Ensure all endpoints in the TargetGroup are healthy and passing health checks. Unhealthy endpoints are automatically removed from the pool.
• Load Balancer Configuration: Verify that the load balancer is correctly configured to route traffic to the TargetGroup.
• Network Configuration: Check network settings to ensure there are no misconfigurations preventing traffic flow.
• Traffic Distribution Policy: Review the traffic distribution policy to ensure it is set up as expected (e.g., round-robin, least connections).

2. Endpoints Failing Health Checks

Problem: Endpoints in the TargetGroup are failing health checks.

Solution:

• Health Check Settings: Review and adjust health check settings (protocol, path, interval, timeout, and threshold) to ensure they are correctly configured.
• Endpoint Status: Ensure that endpoints are operational and configured to respond to health check requests.
• Logs and Monitoring: Use logs and monitoring tools to identify specific reasons for health check failures and troubleshoot accordingly.

3. TargetGroup Creation Fails

Problem: Unable to create a TargetGroup.

Solution:

• Permissions: Ensure your account has the necessary permissions to create and manage TargetGroups.
• Resource Limits: Check if you have reached any resource limits for your Utho Cloud account.
• Configuration Details: Verify that all required details (name, protocol, port, endpoints) are correctly entered.

4. Endpoint Connectivity Issues

Problem: Endpoints in the TargetGroup are experiencing connectivity issues.

Solution:

• Network Configuration: Verify that network settings, including subnets and routing tables, are correctly configured to allow traffic to and from the endpoints.
• Firewall Rules: Ensure that firewall rules are not blocking traffic to or from the endpoints.
• Endpoint Status: Confirm that endpoints are up and running without internal issues.

Error Messages

1. “Endpoint Unreachable”

Error: Endpoint Unreachable

Solution:

• Network Configuration: Check network settings and ensure endpoints are reachable from the load balancer.
• Firewall Rules: Verify that firewall rules allow traffic between the load balancer and the endpoints.
• Endpoint Status: Confirm that endpoints are operational and not experiencing downtime.

2. “Health Check Failed”

Error: Health Check Failed

Solution:

• Health Check Configuration: Review and adjust health check settings to ensure they correctly reflect the health of endpoints.
• Endpoint Status: Ensure that endpoints are configured to respond to health check requests and are operational.
• Logs and Monitoring: Use logs and monitoring tools to identify specific issues causing health check failures.
