Why does Nginx look for the default path instead of containers?

Hello,
I have two containers running on ports 3000 and 3001:

Code:

# ss -tupln
Netid    State     Recv-Q     Send-Q         Local Address:Port          Peer Address:Port    Process

tcp      LISTEN    0          4096                 0.0.0.0:3000               0.0.0.0:*        users:(("docker-proxy",pid=87578,fd=4))

tcp      LISTEN    0          4096               127.0.0.1:35751              0.0.0.0:*        users:(("obfs4proxy",pid=538,fd=3))        
tcp      LISTEN    0          4096                    [::]:80                    [::]:*        users:(("docker-proxy",pid=88606,fd=4))    
tcp      LISTEN    0          4096                    [::]:3000                  [::]:*        users:(("docker-proxy",pid=87585,fd=4))    
tcp      LISTEN    0          4096                    [::]:3001                  [::]:*        users:(("docker-proxy",pid=87608,fd=4))

Nginx configuration is as follows:

Code:

server {
        listen 80;
        server_name localhost.comm;
        error_log  /var/log/nginx/error.system-default.log;
        access_log /var/log/nginx/access.system-default.log;        

        location node1.localhost.comm {
            proxy_pass http://Node1:3000;
            proxy_redirect     off;
            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-Host $server_name;
        }

        location node2.localhost.comm {
            proxy_pass http://Node2:3000;
            proxy_redirect     off;
            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-Host $server_name;
        }
    }

The /etc/hosts file is as follows:

Code:

127.0.0.1       node1.localhost.comm
127.0.0.1       node2.localhost.comm

But I can't see any of the containers:

Code:

# curl node1.localhost.comm
<html>
<head><title>404 Not Found</title></head>
<body>
<center><h1>404 Not Found</h1></center>
<hr><center>nginx/1.25.4</center>
</body>
</html>

The Nginx log is as follows:

Code:

2024/05/08 14:14:58 [error] 28#28: *1 "/etc/nginx/html/index.html" is not found (2: No such file or directory), client: 192.168.32.1, server: localhost.comm, request: "GET / HTTP/1.1", host: "node1.localhost.comm"

What is wrong?

Thank you.
