Web - Server

New here...trying to figure out how to get into the challenge. thanks

What is the challenge you want to accede ?
You just have to click on it, read the informations on the page and click on "start the challenge". A web page should be opening on a new tab (if you are on a web server chall) and you could try to solve it by finding the flag (a password for instance).

Sometime the issue is with AD blocking extension.
