Logging headers going to a backend system

For some reason, my earlier post got blocked-hence reposting my question.

I have a HAProxy running with non-root user and one particular request is failing with HTTP 400 Bad request error. I have started HAP with “-d” and all Im seeing is folowing. Please help me in troubleshooting the issue further.
