Nginx multipe proxy pass locations

I need to proxy pass my domain to 2 different apps! the first one is the main API and the second one is a WebSocket.

My configuration looks like this but it won’t work quite well! when I hit the / it’s fine but when I go in /ws location it shows me default Nginx page 404


server {
    server_name ws.saraf.app;

    listen 443 ssl; # managed by Certbot
    ssl_certificate /etc/letsencrypt/live/ws.saraf.app/fullchain.pem; # managed by Certbot
    ssl_certificate_key /etc/letsencrypt/live/ws.saraf.app/privkey.pem; # managed by Certbot
    include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
    ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot
    
    location ~ / {
	proxy_pass http://127.0.0.1:8080;

Hi @hasanparasteh,

The config looks good to me, all is in order. With that in mind, is there anything listening on port 8889. It seems to me this might be the culprit to further look into.

Please do see If anything is listening to that port. I’m eager to see
