Web challenge - start instance

Hello , i don’t understand how to use the start instance button .
am i supposed to start the instance and then connect to HTB vpn ? (ip address are different) ; or used a other web browser on HTB website ?
if someone can give me some hints - thank you

When you start an instance you are given an IP and port. Simply access it as you would any other webserver, open a new tab in your browser and go to the address e.g.

Good luck
