How to change the host address from localhost to the name of the server?

Hello! My name is vrunda :) I am trying to move a webpage that I created on bonita portal from local host(localhost:8080/bonita) to a server named "sftp://txcslnawb1v" .
I tried to copy the .bar file and the .xml file that I created from my machine to a folder in this server (using filezilla).
After that I tried to access it with this url: http://txcslnawb1v:8080/bonita, unfortunately I don't think this is the correct way since I am getting "unable to connect" on the web browser.
