        proxy_read_timeout 200s;
        proxy_redirect    off;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header Host $host;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto  $scheme;
        client_max_body_size    1000m;
        proxy_http_version 1.1;

        proxy_set_header Connection "upgrade";
 
        if ($remote_addr ~ "172.16.2.53")
        {
            proxy_pass    http://client3;
            break;
