I have 2 droplets, the first one has domain pb82.net, and it works perfectly.
The second one peter-ezzat.net, ip of 18.104.22.168 and the domain doesn't work.
Domain Name: PETER-EZZAT...
Allright, I found your problem. Please post your webserver VHOST config.
The webserver (nginx or apache) probably redirects the domain peter-ezzat.net to www.peter-ezzat.net. I can verify this once you posted the VHOS...
