The location with websocket proxy you are testing is on port 80 
too.  Do you see other requests to the host in access log?

The fact that it helps indicate that connection is ok (that is, 
you should see it in access log once it completes - unless you 
disabled access logging or looking into wrong logs), but isn't 
considered to be upgraded to a websocket protocol for some reason.

Most obvious reason I can think of is an old version of nginx 
actually running, the one without websocket proxy support 
(something before 1.3.13 instead of 1.4.1 you claim in your 
initial message).  It's trivial to check by looking into Server 
header line returned.

If still no lock, try configuring a debug log and obtaining one 
while trying a websocket request, see 
http://nginx.org/en/docs/debugging_log.html for details.
