Windows phone emulator can't connect to UDP port error

I'm using Visual Studio 2015 Community on Windows 10. The Windows Phone 8.1 Emulator used to work just fine, until I tried to shut Hyper-V down (unsuccessfully).

Hyper-V

When rebooting, Windows displayed that there is a problem and that it won't be able to complete the task and that it will revert to its original state.

When it started again Hyper-V was still activated, but a problem started showing up when I started the emulator from Visual Studio.

And after a few minutes it prompts this error:

UDP Port

I know that the virtual machine is running because I can access it from the Hyper-V Manager:

Hyper-V Manager

I tried all solutions available online:

  1. Deleting the virtual machine, and restarting Visual Studio as administrator.
  2. Deleting the internal Switch and re-creating it (manually and by running the emulator from Visual Studio) Switch
  3. Shutting down the FireWall.
  4. Sharing the WIFI internet access to the virtual network.

Nothing worked. Anyone has seen this before?

I had a similar problem and tried many solutions and got the emulator working by doing the below steps:

  1. Remove all the virtual switches from "Virtual Switch manager"
  2. Restart your system.
  3. Goto Control Panel -> Network and Internet -> Network and Sharing Center -> Advanced sharing settings
  4. And enable "Turn on Network discovery" and "Turn on file and printer sharing" for all network profiles. Sharing screen for reference
  5. Start emulator.

Done.

I have no idea how, but after a number of reboots the emulator works again. This is maybe some weird bug with Hyper-V that was fixed silently.
