Fortnite save the world error message what to do?

I just bought Save the World and played the tutorial. Now I want to play my first Strumschild mission, but every time the mission starts I get an error message. My internet connection is said to have been interrupted. However, I have had no internet problems with any other games. The Battle Royale mode also worked perfectly for me. Please help me! Thanks in advance! I have attached a picture of the error message.

Just try restarting the pc maybe it is just a small mistake or you just pull your LAN cable and then you may put it back in maybe it is better

Write it epic games. Maybe they'll help you.
