The message indicate that upstream server returned invalid
response, or at least nginx thinks it is invalid. If you think
that response returned is valid, it's good idea to actually
provide what was returned, as well as nginx's debug log.

See here for some more hints:

No, "chunked_transfer_encoding" is to disable use of chunked
transfer encoding with clients by nginx. The message complains
about what's returned by your backend server.
