Could not connect to server Minecraft Windows 10

Hi…

We have just tried the Minecraft mod tutorial, and clicked the “play” icon to deploy.

We are on Minecraft for Windows 10, so we type in the Minecraft console:

/connect mc.tynker.com/blah

Minecraft then doesn’t connect, and we get an error message:

Could not connect to server:
ws://mc.tynker.com/blah

Anyone manage to get this working?
