Can someone help me with this

[Quốc Bảo Võ]

Hi, I'm just getting started with Apache Cloudstack. I have installed it step 
by step at this site: 
http://docs.cloudstack.apache.org/en/4.14.0.0/quickinstallationguide/qig.html. 
But when I run it on the browser, it can't connect to UI interface and I don't 
know how to fix it
