The above logs are coming from cups logs. Is there any hit for this?

You can configure your CUPS server to listen on different interfaces. Please read the docs of your CUPS server.

@harwey @whatoeat2night
It just a error solution !!!
Finally i solved it by Nginx

this is my nginx config

server{
    listen 632;
    access_log /var/log/nginx/cups_access.log;
    error_log /var/log/nginx/cups_error.log;

    location / {
            proxy_pass  http://127.0.0.1:631/;
    }

}

I have try to listen new port 632 proxy to 127.0.0.1:631 its down
i dont know why? maybe cups web open in windows different from linux :) 💯
