try_files in nginx.conf not working

I'm working with an angular 2 app, nginx and docker. Everytime I'm reloading a page with /site it gives me a 404. My server block looks like this right now:

server {
listen 0.0.0.0:80;
listen [::]:80;

root /var/www/project/html;

index index.html;

server_name project.com;

location / {
    try_files $uri $uri/ /index.html;
}}

I have tried a lot, and have seen ALL other stackoverflow questions and have tried every possibility. But nothing works. Can someone please help?

UPDATE: The whole nginx.conf:

user  nginx;
worker_processes  auto;

error_log  /var/log/nginx/error.log warn;
pid        /var/run/nginx.pid;


events {
    worker_connections  1024;
}


http {
    include       /etc/nginx/mime.types;
    default_type  application/octet-stream;

    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

    access_log  /var/log/nginx/access.log  main;

    sendfile        on;
    #tcp_nopush     on;

    keepalive_timeout  65;

    #gzip  on;

    include /etc/nginx/conf.d/*.conf;
    include /etc/nginx/sites-enabled/*;
}

the sites-enabled/default:

    server {
listen 0.0.0.0:80;
listen [::]:80;

root /var/www/project/html;

index index.html;

server_name project.com;

location / {
    try_files $uri $uri/ /index.html;
}}

And the Dockerfile:

FROM nginx

COPY ./docker/sites-enabled /etc/nginx/sites-enabled
COPY ./docker/nginx.conf /etc/nginx/nginx.conf
COPY ./dist /var/www/project/html
COPY ./dist /usr/share/nginx/html
EXPOSE 80

In your nginx.conf, you are loading additional configs from two locations:

include /etc/nginx/conf.d/*.conf;
include /etc/nginx/sites-enabled/*;

The second one loads your sites.enabled/default config with the server name project.com.

The first one, though, loads the default config default.conf which is part of the nginx docker image per default. That config looks similar to 

server {
    listen       80;
    server_name  localhost;

    ....

    location / {
        root   /usr/share/nginx/html;
        index  index.html index.htm;
    }

    ....
}

So if you try to access your site with localhost, your sites-enabled/default is never used (since you specified the server_name project.com and that doesn't match with localhost). Instead the request runs in the default.conf since there the server_name is localhost.

And in the default.conf the location part is:

location / {
        root   /usr/share/nginx/html;
        index  index.html index.htm;
}

That means, if you just go to localhost, the index.html is served and everything works as expected. But as soon as you try accessing localhost/something, Nginx is trying to find the file/directory /usr/share/nginx/html/something which doesn't exist (-> 404).

So you have to options:

  1. Remove include /etc/nginx/conf.d/*.conf; from your nginx.conf (or delete the default.conf) and change the server_name in your sites-enabled/default to localhost. Then your request will run into your config.

  2. Add the try_files $uri $uri/ /index.html; to the location in the default.conf like you have it in your sites-enabled/default.

I would recommend the first solution, do not include the default.conf and change your server_name to localhost in your sites-enabled/config. If you later need your real domain, you can still use regex to match for either localhost or your domain.
