There’s no information here. A dump of code and saying it doesn’t work doesn’t help.

To be honest this isn’t the place to ask as it isn’t part of our courses. You should post a question in the discord…

Yoy could also download the shooter multiplayer sample Lyra from epic and examine the code as well.

Saying that, you’ll probably need an RPC on a fire event so the server knows to line trace otherwise the server won’t know you’re shooting. Then, on hit you’ll have to send out updates to the player health.
