Solved: WWAHost.exe remote endpoint was not reachable error in JavaScript Windows Store App

I was working on my office machine. While working I opened a JavaScript based Windows Store Application. When I tried to run application I got following exception,


I was baffled due to this exception. After sort of research I found that I was on VPN. I have no idea why on VPN this exception occurred. But to get rid of this exception you need to follow these two steps

  1. Closed all connections to VPN
  2. Restart machine

After performing above two steps you should not get above exception. I hope this quick post is useful. Thanks for reading.
