Thanks for reporting this @roshanprince402

This document explains best what SSLWantReadError means:

Looks like we are running exactly into same issue when trying to flush uploaded file chunks to upstream server i.e. Upstream server socket is not ready while we are trying to read/write from it. I'll take a look into it. Thank you!!!

#368 should address this issue, PTAL. This will be released next week via pip.
