Can't Load World URL's

I don’t know what’s going on, I got foundry earlier today so I can dm for campaigns with some online buddies. I don’t have the time to make a campaign currently and so I found a one shot online, yet whenever I paste the URL in the box it gives me an error that I can’t find any help for online. pls help I want to play DnD :frowning:

Hi there,

The URL you’re trying to use may have expired or changed.
Can you try downloading this one-shot campaign and using our Import Wizard to get it into the Forge?
Using our Import Wizard is prefered method and most likely to work, please check out THIS document here for more info.
