Both requests do look basically correct just like the nginx's and 
curl's behavior. You didn't supply any credentials for 
authentication to continue.

You can use -u curl option to explicitly specify <user:password> 
on the command line either -n option to read 'em from your netrc. 
Curl will at least try to authenticate itself with the supplied 
credentials then.

You could also find this document useful
