The domain name has been mapped to the port 80,but I cant get expected infomation visiting the site

"www.cni-expo.com" has been mapped to the ip, 59.108.85.207. I use the web server, which was started at 80 port. then I think I could get some correct info by "www.cni-expo.com" .but I got this.enter image description here

"www.cni-expo.com" has been mapped to the ip, 59.108.85.207. I used nginx as web server, which was started at 80 port. then I thoutht I could get some correct info by "www.cni-expo.com" .but I got this.

Then I mapped another domain name, "gjy.yongdd.com" to the same ip.I

so my quetion is why it went like this? where is the problem? how could i have been visited?
