Issues with reverse proxy and serving from subdirectory.

[sonicnkt]

I added the following config option to solving issues using nginx as reverse proxy and serving the app in the subdirectory like subdomain.example.com/glauth:

SERVER_NAME = os.environ.get('BASE_URL')

I still cant get this to work tho and only getting 404 erros when trying to access anything. Any help on this would be very much appreciated :)

I tried:

server {
    listen 443 ssl http2;
    server_name subdomain.example.com;

    include /etc/nginx/ssl-stuff.conf;
    add_header Strict-Transport-Security    "max-age=31536000; includeSubDomains" always;
    add_header X-Frame-Options              SAMEORIGIN;
    add_header X-Content-Type-Options       nosniff;
    add_header X-XSS-Protection             "1; mode=block";


    client_max_body_size 100M;

    location ~/glauth(.*) {
        proxy_pass http://127.0.0.1:3005$1;
        proxy_set_header    X-Real-IP           $remote_addr;
        proxy_set_header    X-Forwarded-For     $proxy_add_x_forwarded_for;
        proxy_set_header    X-Forwarded-Proto   $scheme;
        proxy_set_header    Host                $host;
        proxy_set_header    X-Forwarded-Host    $host;
        proxy_set_header    X-Forwarded-Port    $server_port;

        }
}

as well as

  location /glauth/ {
        proxy_pass http://127.0.0.1:3005$1;
        proxy_set_header    X-Real-IP           $remote_addr;
        proxy_set_header    X-Forwarded-For     $proxy_add_x_forwarded_for;
        proxy_set_header    X-Forwarded-Proto   $scheme;
        proxy_set_header    Host                $host;
        proxy_set_header    X-Forwarded-Host    $host;
        proxy_set_header    X-Forwarded-Port    $server_port;

        }

Settings the SERVER_NAME to subdomain.example.com/glauth makes the all links look correct but it still results in 404 errors. Without the subdirectory everything works without any issues even without the server_name set.

The issues is probably with some of the proxy_header settings but i dont have much experience with this.
