asp.net core on linux with nginx routing doesn't work - linux

Question

I've created an ASP.NET Core MVC application and deployed it into Linux server. When I go to sitename.com browser shows up the Home/Index page without any problem.
But when I try to go sitename.com/Home/Index or another controller like sitename.com/Admin/Login nginx throws a 404 Not Found error. What should be the problem?
Here is my Startup.cs/Configure method.
public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
{
loggerFactory.AddConsole(Configuration.GetSection("Logging"));
loggerFactory.AddDebug();
if (env.IsDevelopment())
{
app.UseDeveloperExceptionPage();
app.UseBrowserLink();
}
else
{
app.UseExceptionHandler("/Home/Error");
}
app.UseStaticFiles();
app.UseSession();
app.UseMvc(routes =>
{
routes.MapRoute(
name: "default",
template: "{controller=Home}/{action=Index}/{id?}");
});
}
Here is my website config from sites-available folder
server {
listen 80 default_server;
listen [::]:80 default_server ipv6only=on;
root /var/www/sitename.com;
index index.html index.htm;
server_name sitename.com www.sitename.com;
location / {
try_files $uri $uri/ =404;
proxy_pass http://127.0.0.1:5000;
}
and nginx.conf
user www-data;
worker_processes 4;
pid /run/nginx.pid;
events {
worker_connections 768;
}
http {
sendfile on;
tcp_nopush on;
tcp_nodelay on;
keepalive_timeout 65;
types_hash_max_size 2048;
include /etc/nginx/mime.types;
default_type application/octet-stream;
access_log /var/log/nginx/access.log;
error_log /var/log/nginx/error.log;
gzip on;
gzip_disable "msie6";
include /etc/nginx/conf.d/*.conf;
include /etc/nginx/sites-enabled/*;
}
mail {
}

Answer 1

Remove try_files $uri $uri/ =404; as it's testing if a certain url exists on the file system and if not return 404.
But /Home/Index is a route, which do not map to an existing file but to controller action, hence you get the 404 error.

Answer 2

To help someone searching on Google
I was getting 404, but I realized that ASP Net only accepts 1 server by name
Example NOT POSSIBLE:
server{
listen 80;
listen [::]:80;
server_name example.com;
location /asp_app_ONE {
proxy_pass http://0.0.0.0:3001;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection keep-alive;
proxy_set_header Host $host;
proxy_cache_bypass $http_upgrade;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
}
location /asp_app_TWO{
proxy_pass http://0.0.0.0:3002;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection keep-alive;
proxy_set_header Host $host;
proxy_cache_bypass $http_upgrade;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
}
}
Example OK:
server{
listen 80;
listen [::]:80;
server_name appONE.example.com;
location / {
proxy_pass http://0.0.0.0:3001;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection keep-alive;
proxy_set_header Host $host;
proxy_cache_bypass $http_upgrade;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
}
}
server{
listen 80;
listen [::]:80;
server_name appTWO.example.com;
location / {
proxy_pass http://0.0.0.0:3002;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection keep-alive;
proxy_set_header Host $host;
proxy_cache_bypass $http_upgrade;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
}
}
