Amazon Bedrock Access Problems

For Bedrock failures, first separate region/model configuration from authorization, quota, request, and network problems.

Diagnose

1. Confirm the AWS region and exact model identifier.
2. Inspect the full API error rather than only the HTTP status.
3. Verify the application's IAM principal has the required Bedrock actions.
4. Check account/model-access configuration and service quotas.
5. Reduce the request to a minimal known-good invocation.
6. If applicable, trace the network path from the workload to the service.

Fix → Verify → Prevent

Apply the smallest confirmed change, test a minimal request, and preserve the successful configuration as code or runbook guidance.
