To use chrome://net-export/
- Open the Chrome browser
- Open this url "chrome://net-export/". Select "include raw bytes" and click "Start Logging to disk" (Chrome will ask you for the location of the file where log will be saved)
- Make sure the tab where net-export is open stays open, closing it will stop the logs too.
- Navigate the application causing the problem
- Once the problem replicates go back to "chrome://net-export/" tab and click "Stop Logging"
This log can then be loaded by Chrome.

- Traffic shaper on the ISP providing Server connectivity to Mid-tier server capping bandwidth

- Some chrome extensions like https://digitalguardian.com/ found to redirect from POST backchannel request to GET, but without the POST payload, therefore the request is invalid for Mid-tier purposes
