Most likely, the authentication request appears due to your
browser doing automatic requests to /favicon.ico or something
like. Try adding

location = /favicon.ico {
return 404;
}

to see if it helps.

Config looks correct and should work. Try testing it by hand
(e.g. nc/telnet/fetch/wget/curl) to see if it actually works. See
above for a possible cause of the authentication request.
