Running Multiple Web Applciations on the Same LAN Server nginx - nginx

Question

I'm serving 2 docker containers on a LAN network, a cloud server on port 5234 and a flask application other on 8080.
I'm trying to use nginx as a reverse proxy to run them both on the same ip with different extensions. My config:
server {
listen 80 default_server;
server_name 192.168.1.23;
location /web {
proxy_pass http://127.0.0.1:8080;
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;
access_log /var/log/nginx/flaskapp.access.log;
error_log /var/log/nginx/flaskapp.error.log;
}
location /cloud {
proxy_pass http://127.0.0.1:5234;
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;
access_log /var/log/nginx/nextcloud.access.log;
error_log /var/log/nginx/nextcloud.error.log;
}
}
but I'm getting a 502 Bad Gateway when accessing 192.168.1.23/web or 192.168.1.23/cloud.
In flaskapp.error.log:
connect() failed (111: Connection refused) while connecting to upstream, client: 192.168.1.72, server: 192.168.1.23, request: "GET /web HTTP/1.1", upstream: "http://127.0.0.1:8080/", host: "192.168.1.23"
In nextcloud.error.log:
recv() failed (104: Connection reset by peer) while reading response header from upstream, client: 192.168.1.72, server: 192.168.1.23, request: "GET /cloud HTTP/1.1", upstream: "http://127.0.0.1:5234/cloud", host: "192.168.1.23"
Is there a way to run multiple web applications on the same ip like this or using different ports?

Answer 1

0.0.0.0 is not a valid IP Address. Try 127.0.0.1 which refers to the local host.
like this:
proxy_pass http://127.0.0.1:8080;
