Died function not working on reset, but does when killed manually?

Hi guys.

So I'm having this terribly annoying issue and I can't find a fix.

When a player dies, I want the script to print a simple string "Died!". However, when the player dies the script just seems to not care and looks the other way. No prints, no errors, nothing!

The funny thing however; when I manually set my Health to 0 in the Humanoid (Workspace > PlayerName > Humanoid), the function DOES fire.

I'm using a server-sided script in ServerScriptService, with the following code; (Has been shortened for simple reading, I made sure no parts are missing.

function died()
        print("Died!")
    end 

game.Players.PlayerAdded:Connect(function(player)

    player.CharacterAdded:connect(function(character)
        character:WaitForChild("Humanoid").Died:connect(function()
            died()
        end)
    end)

end)

Any ideas??
