I have a service running on Docker on port 3000 inside a Raspberry Pi. I added a reverse proxy on nginx to serve that service.
server {
listen 80;
server_name pizza.pi;
location /my-dashboard {
# Pass requests to the backend service
proxy_pass http://127.0.0.1:3000;
proxy_http_version 1.1;
# WebSocket and other headers
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
proxy_set_header Host $host;
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 $scheme;
# Ensure proper path forwarding
rewrite ^/my-dashboard(/.*)$ $1 break;
}
}
When I go to http://pizza.pi/my-dashboard from inside the Pi, I am correctly seeing the service (NextJS) running. However, when I try to access the same URL from another computer on the network, I get 404 and I see the following logs on nginx:
[debug] 16756#16756: *45 test location: "/"
[debug] 16756#16756: *45 using configuration "/"
...

[debug] 16756#16756: *45 http set discard body
[debug] 16756#16756: *45 HTTP/1.1 404 Not Found
The service is however accessible on the network if I specify the port http://pizza.pi:3000/my-dashboard but then I don't get any logs on nginx, which tells me that nginx is somehow bypassed in this case (just a guess, as I'm not that familiar with such configs).
I've tried playing around with trailing slashes in the configuration but to no avail.
What am I missing here? How can I get http://pizza.pi/my-dashboard to work from any device on the network?
