Why am I unable to get past this download point in UE4 prerequisites?

I just want to play Dauntless. I downloaded the game from Epic Launcher. When I try to run the game, it prompts me to download UE4 prerequisites (64x). When the download comes to almost half way, it stops making progress. I left the download running all night and it still hasn’t moved! I installed the unreal engine directly from Epic Launcher, but that did not resolve the issue. I uninstalled and reinstalled Dauntless, but the download stops at the same point again. I just want to play Dauntless but I am unable to get past that stopping point in the download!
