Allow ETP Client connections on Microsoft Edge
By default, Microsoft does not allow Universal Windows Platform (UWP) apps such as Microsoft Edge to communicate with a network server that's listening on the localhost. When the proxy is enabled, communication with the localhost is necessary. Complete this procedure when using the client with ETP Proxy.
- Open a PowerShell window.
Enter this command to see the package name of Microsoft Edge:
- Take note of the PackageFamilyName value.
To allow loopback connections (connections through the localhost), enter this
CheckNetIsolation LoopbackExempt -a -n="<PackageFamilyName>"
where <PackageFamilyName> is the Package Family Name that you see in step 3.
- Use your enterprise patch management system such as Microsoft System Center Configuration Manager or KACE to distribute this change to Edge browsers across your organization.
