Some people were having problems when they ran their P4 assignments from a secure JSBin or from their handin directory.
the problem is… the link for fakeserver was an http link, not a secure link (https). if your program is from a secure place (it was from https://), then it is a security error to load a non-secure thing
the answer:
load fakeserver via a secure link:
https://pages.cs.wisc.edu/~cs638-1/Puzzle4/fakeserver.js
