Don't work well the SetNetworkOwner

Server:

local ReplicatedStorage = game:GetService("ReplicatedStorage")

make the push all client (like add code on server that will fire the enemyClient and add the code on client that will receive the push), if a player wanna cheat he can still mess around with movement system

i solved the problem, i only changed two things and it worked, this is the server script that solved it:

	hrp:SetNetworkOwner(player) -- *to hrp:SetNetworkOwner(nil)*

	local rawImpulse = pushDir * FUERZA * hrp.AssemblyMass

	local maxImpulse = 66 * hrp.AssemblyMass
	if rawImpulse.Magnitude > maxImpulse then
		rawImpulse = rawImpulse.Unit * maxImpulse
	end

	print(rawImpulse.Magnitude)

	hrp:ApplyImpulse(rawImpulse)

	task.delay(IMPULSE_TIME, function()
		if hrp then
			hrp:SetNetworkOwner(nil) -- *to hrp:SetNetworkOwner(targetPlayer)*
		end
	end)
