My module was working days ago, but Roblox broke it, how do I fix it?

The module was working days ago but roblox then broke it when i just changed the HTTP link (because everytime I restart the server, it gives me a new link.) ModuleScript was required from serverside script.

local module = {}

	p.Size = Vector3.new(13.66, 7.68, 1)

	p.BrickColor = BrickColor.new("Institutional white")
	p.Material = Enum.Material.SmoothPlastic
	p.TopSurface = Enum.SurfaceType.Smooth
	p.Transparency = 1
	p.Massless = true
	p.Anchored = true
	p.CanCollide = true
	p.CastShadow = false
	p.Locked = true

Help is appreciated! PS: Yes I have enabled HTTPService
