your apache return 404 error to nginx, and nginx return 404 error to client.
there is no problems with nginx - it work as expected.

useless. make tcpdump of tcp session between nginx frontend
and apache backend and see - correct request or not correct.

btw, apache save the request to logfile: "HEAD /MYLER.htm HTTP/1.0"
there is nothing incorrect in this request, from my point of view.

x> Can it be a change in the HTTP 1.0 and HTTP1.1 diffirence?

make HTTP/1.1 and HTTP/1.0 request
to backend from curl and get to know.

also make direct request to 80 port and 81 port of apache,
*don't using nginx at all* and also see - it work as expected or not.

for all four requests ( HTTP/1.1 or HTTP/1.0 ) x ( port 80 or port 81 )
use only curl, not web browser. after such debug situation must be clear.
