Looks for me that there is a problem that an IPv6 Adress is given to an http client without square brackets.

Hello @rherold thanks a lot for participating in the community.

very interesting and thanks a lot for the detailed logs, nonetheless i cannot reproduce the issue.

In my case the auto NAT of docker network works well if i directly access 127.0.0.1:9000 or if i use a docker jwilder proxy.

Do you confirm that a direct curl 127.0.0.1:9000 from the machine works as expected ?

My suspicion here is on the proxy_pass 127.0.0.1 which does not indicate IPv6 usage, could you replace it with [::] ?

Also could you clarify your setup on the reverse-proxy, i guess it is not installed with docker ?

in my case i use a docker jwilder proxy with :

error_log /var/log/nginx/error.log debug;

events {
    worker_connections 1024;
}

http {
    upstream backend {
        server [2001:db8:3::91]:9000;
    }

    server {
        listen 80;
        listen [::]:80;

        location / {
            proxy_pass http://backend;
            proxy_set_header Host $host;
            proxy_set_header X-Real-IP $remote_addr;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        }
    }
}

and if i IPv4 curl ‘http://127.0.0.1:8080’

i do see in my logs:

proxy-1  | 192.168.3.1 - - [24/Jun/2025:14:41:32 +0000] "GET / HTTP/1.1" 200 1698 "-" "curl/8.7.1"
proxy-1  | 2025/06/24 14:41:32 [info] 29#29: *15 client 192.168.3.1 closed keepalive connection

And from sonarqube:

2001:db8:3:0:0:0:0:3 - - [24/Jun/2025:14:41:32 +0000] "GET / HTTP/1.0" 200 - "-" "curl/8.7.1" "b0691181-4042-4a2a-b92c-dc6bf8edc140" 8

This indicates an IPv4 request to nginx, which then send IPv6 to sonarqube.

Happy to debug this further,

Regards,

Jérémy.
