I'm trying to pass off all calls to /api to my webservice but I keep getting 404s with the following config. Calls to / return index.html as expected. Does anyone know why?

   upstream backend{
server localhost:8080;

 server {

        location /api {
        proxy_pass http://backend;

        location / {

        root /html/dir;


More info here:

adept@HogWarts:/etc/nginx/sites-available$ curl -i localhost/api/authentication/check/user/email

  • Is the 404 coming from nginx or from the backend? – Wing Tang Wong Apr 22 '13 at 22:51
  • My understanding is its coming form nginx, I put some more info in the question to help. – Roge Apr 22 '13 at 22:53
  • done chown -R on /html/dir? – Simon Hayter Apr 22 '13 at 22:59
  • No, but there is no problem with the / location; calls to localhost return index.html from /html/dir as expected the problem is with the /api/ location – Roge Apr 22 '13 at 23:00
  • location /api { proxy_pass backend; } Needs to be this location /api/ { proxy_pass backend; } – Roge Apr 22 '13 at 23:45

I think you're missing a slash in your proxy_pass, see http://nginx.org/r/proxy_pass.

It should be proxy_pass http://backend/;, if you want to map /api locationfrom Nginx to / from upstream, otherwise, it'll be going to /api on upstream, too.
