Hi Gurus

My lab environment is

Nginx IP: 192.168.16.206
Four Web Server: 192.168.16.201-204

My nginx.conf is

http {
upstream myapp1 {
server 192.168.16.201;
server 192.168.16.202;
server 192.168.16.203;
server 192.168.16.204;
}
server {
listen 80;
location / {
proxy_pass http://myapp1;
}
}
}

from web brower, i use http://192.168.16.206 to access the web server. the web brower redirect "http://192.168.16.206" to "https://myapp1/"
then i got error "myapp1’s server DNS address could not be found." error.

Could you please give me some suggestions about this? thanks so much for your feedback.
