Not found error with two Node projects served by NGINX with Docker

Solution 1:

You should use only one "server" since they share server_name and port

server {
    listen 80;
    listen [::]:80;
    server_name  127.0.0.1;

    # Logging
    access_log             /var/log/nginx/access.log;
    error_log              /var/log/nginx/error.log;

    location /project-a {
        proxy_pass http://website_a:8301/project-a;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header Host $host;
        proxy_redirect off;
        # max uploadable file size
        client_max_body_size 4G;
    }

    location /project-b {
        proxy_pass http://website_b:8302/project-b;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header Host $host;
        proxy_redirect off;
        # max uploadable file size
        client_max_body_size 4G;
    }

}
