Fortnite rdw network connection lost?

Hello recently i bought rdw for 20 euro and the first thing didn't work but the first mission doesn't work why can someone help me? My internet is great too

It was the same with me.

go into the epic launcher, then on the setting of fortnite, which is shown in the library ubd check the save the world. Then unfortunately you have to download 3GB. When it is downloaded you can play. (So that's how it is on my pc) I don't know how it is on ps4, probably something like that.
