Host is player taking all damage from players no mater what

Question

Hi I’m new on the forums so sorry if this is the wrong place, but I need help with this. I’m working on a fps and when ever I shoot its doing some real weird stuff. So when ever the “Host” player shoots another player nothing happens (not good) and if 2 non host players shoot each other nothing happens but if any other player shoots the host he takes the damage
I have no idea how this forum stuff works so I don’t know if i need like anything special in the post but uh heres the code for calling out a hit:


		if Input.is_action_pressed("fire"):
	# second shotgun
			if guntype == 6:
				if shot_2load > 0 && shot_02am.is_playing() == false:
					shot_2load = shot_2load-1
					hud.rounds = shot_2load
					shot_02am.queue("fire")
					if self.is_in_group("Team 1") == true:
						for r in shot_02cast.get_children():
							if r.is_colliding():
								if r.get_collider().is_in_group("Team 2"):
									r.get_collider().shot2hit.rpc_id(r.get_collider().get_multiplayer_authority())
									print("a player was shot")
					if self.is_in_group("Team 2") == true:
						for r in shot_02cast.get_children():
							if r.is_colliding():
								if r.get_collider().is_in_group("Team 1"):
									r.get_collider().shot2hit.rpc_id(r.get_collider().get_multiplayer_authority())
									print("a player was shot")

this is the shot function

@rpc("any_peer")
func shot2hit():
	var qty = 6
	subtracthealth(qty)
the part that subtracts health and  respawns you


func subtracthealth(qty):
	if $MultiplayerSynchronizer.get_multiplayer_authority() == multiplayer.get_unique_id():
		health = health - qty
		hud.health = health
		if health <= 0:
			hud.health = 0
			$Timer.start

func _on_timer_timeout() -> void:
	respawn()

func respawn():
	if $MultiplayerSynchronizer.get_multiplayer_authority() == multiplayer.get_unique_id():
		global_position = spawnpoint.global_position
		health = 100
		shotammo = 6
		shot_2load = 2
		guntype = 55

Any help would be greatly appreciated :)
