Hi Anggadika,

Did you read the example' comment?

---

from the source:

// This loopback host is for demo purpose. If this port is not

// available on your machine you need to update this URL with an unused port.

private const string LoopbackHost = "http://127.0.0.1:52475/";

Have you checked some other port? One more restriction, you should consider, is all ports below 1000 are considered by some environments as special and are not provided to regular programs. Did you select such a port explicitly or implicitly (take in mind that HTTP matches by default to port 80 and HTTPS - to 443)? Such ports can be forbidden even when the OS doesn't set such restrictions (it's environment restriction for better portability). Review your settings.

Good luck.
