Removal of server from nginx load balancer does not reflect after nginx reload

Hi,
I am using nginx 1.8.0 as a load balancer.

Below is the configuration snippet:

    upstream appservers {
    least_conn;
    server 10.21.3.123:8083;
    server 10.21.3.125:8083;
}

server {
listen 443 ssl spdy backlog=2048;
add_header Strict-Transport-Security “max-age=31536000;
includeSubDomains”;

add_header Alternate-Protocol 443:npn-spdy/3;

ssl_certificate
/etc/nginx/click.rummycircle.com/click.rummycircle.com.crt;
ssl_certificate_key
/etc/nginx/click.rummycircle.com/click.rummycircle.com.key;

ssl_ciphers
ECDHE-RSA-AES256-SHA384:AES256-SHA256:AES256-SHA256:RC4:HIGH:!MD5:!SSLv2:!ADH:!aNULL:!eNULL:!NULL:!DH:!ADH:!EDH:!AESGCM;
ssl_prefer_server_ciphers on;
ssl_protocols TLSv1 TLSv1.1 TLSv1.2;

    location / {
             #  log_format postdata '$remote_addr - $remote_user

[$time_local] ’
# '"$request" $status $bytes_sent ’
# ‘"$http_referer" “$http_user_agent”
“$request_body”’;
# access_log /home/deploy/nginx_logs/new_access.log
postdata;
proxy_set_header Host $http_host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For
$proxy_add_x_forwarded_for;
proxy_pass http://appservers;
}
}

Nginx is balancing the load between our 2 servers: 10.21.3.123 and
10.21.3.125. I want to remove one server from the load balancer at
runtime
without any packet loss. So I removed i by changing the configuration
like
below:
upstream appservers {
least_conn;
server 10.21.3.123:8083;
}

Then I reloaded nginx: sudo service nginx reload
I checked with nginx -t that Nginx successfully reloaded.
However, it still continues to send new requests to the removed server.
Please assist.

Hi,

Are you using free Nginx or Nginx Plus? Per my memory, server group
reconfigure without restart is a Plus only feature.
