Nginx returning 404 on any path except / (proxy_pass)

manpreet Best Answer 2 years ago

I am using nginx as a reverse proxy to serve my various node and react applications. Basically I set a subdomain for each application.

I can query https://demo.myapp.com/ and it gets passed to the correct underlying app but if I query https://demo.myapp.com/login I get a 404. note that I get "404 Not Found" as plain text, no html no nothing.

I find this odd because I copy pasted the config of my other apps and I can definitely callhttps://myotherapp.myapp.com/login. I have looked online but I didn't find any help on this matter (because I didn't really find a way to formulate my problem ?)

Here's my config (domain names are anonymized but it's exactly the same structure)

    server {
        listen 80 default_server;
        listen [::]:80 default_server;
        server_name _;
        return 301 https://$host$request_uri;
}

# this one works fine when I call sc.example.io/login
server {
    server_name sc.example.io;

    location / {
             proxy_pass http://127.0.0.1:5102;
    }

    listen 443 ssl; # managed by Certbot                                                                                                                                                                    
    ssl_certificate /etc/letsencrypt/live/example.io/fullchain.pem; # managed by Certbot
