- Try to search for the latest occurrence of the crash trace from crash portal. - For crash issues:
- Always check for the latest occurrence from the crash portal.

- Fragment download is successful.
- Ensure License is acquired from the licensing server.
- Ensure the pipeline is constructed successfully.
- Ensure the pipeline received the first video segment from the callback.
- TDK related issues
- Instead of bringing up TDK setup, we can run directly with aampcli binary to reproduce issue.
- For any config mismatch or not reflected issues from fog or aamp.
- Compare the automation logs and box logs to find any mismatch.
- Check the latest codebase if the variables are present.
- For any playback tune failures during STB standby mode or when XRE connection is disconnected.
- Check why receiver is sending the tune request.
- Request receiver team to have a look, as tune during standby or disconnected state is an invalid scenario.
- HTTP proxy feature is targeted for third party application vendors who don't support IPv6 addressing right now. To tackle v6 addressing issue, vendors will be using a 6to4 proxy to route their traffic.
- Don't use RFC/aamp.cfg to configure http-proxy for Comcast IP_Linear playback.
- http-proxy configuration only valid for Comcast VOD and CDVR content.
