Can't open localhost in Microsoft Edge (Project Spartan) in Windows 10 preview

Question

I installed Windows 10 preview and installed IIS.

Open \"http://localhost\" in Project Spartan can\'t connect.

IE has no problem. What\'s the problem?

Answer 1

Microsoft Edge runs with network isolation by default for security reasons. To enable loopback and debug your localhost server run the following command from an elevated shell if you have 10158 or newer:

CheckNetIsolation LoopbackExempt -a -n=Microsoft.MicrosoftEdge_8wekyb3d8bbwe

or

checknetisolation loopbackexempt -a -p=S-1-15-2-3624051433-2125758914-1423191267-1740899205-1073925389-3782572162-737981194

or this one if you have an older version

CheckNetIsolation LoopbackExempt -a -n=Microsoft.Windows.Spartan_cw5n1h2txyewy

In a future update, you’ll be able to enable localhost loopback support using about:flags.
