What's the difference between a 403 error and a 404 error on Roblox?

A 403 error (Forbidden) means you're not authorized to access the resource, while a 404 error (Not Found) means the resource doesn't exist. A 403 is a permission issue, whereas a 404 is a resource location issue. For example, a 403 might occur if you don't have access to a private game, while a 404 might occur if a game ID is incorrect.
