Troubleshoot common issues for CDN and MediaTailor integrations

Incorrect caching settings: If your CDN caches personalized manifests, viewers may see ads intended for other users.

Solution: Configure your CDN with a cache TTL of 0 for manifest requests to MediaTailor.

Origin request failures: If your CDN can't reach MediaTailor, then manifest requests will fail.

Solution: Check network connectivity between your CDN and MediaTailor. Verify your CDN properly forwards the correct headers.

Session parameter issues: Missing or incorrect session parameters can cause personalization failures.

Solution: Ensure that your player is correctly appending all required session parameters to the manifest requests.

Segment path rewriting: Incorrect CDN configuration may rewrite segment URLs improperly.

Solution: Verify your CDN correctly handles segment URLs. Ensure it doesn't modify paths in a way that breaks references.

CORS configuration: Missing or incorrect CORS headers can prevent browsers from loading segments.

Solution: Configure your CDN to pass the appropriate CORS headers for segment requests.

Cache miss storms: During high-traffic events, multiple cache misses can overwhelm origin servers.

Solution: Implement request collapsing and origin shield capabilities to reduce origin load during traffic spikes.

Low cache hit ratio: If your CDN frequently requests content from the origin, then performance will suffer.

Solution: Analyze the cache hit ratios by content type and adjust the TTL settings to improve caching efficiency.

Geographic distribution: Viewers distant from CDN edge locations may experience increased latency.

Solution: Review your CDN edge location distribution. Add capacity in regions with high viewer concentrations.

Origin capacity limitations: If your origin servers are overloaded, then response times will increase.

Solution: Implement origin request limiting. You can also increase origin capacity or improve caching to reduce origin load.
