Article ID: 2778122 - View products that this article applies to.

Symptoms

If you use an Internet proxy server that requires authentication, you may encounter problems when you use apps that connect to the Internet.

Proxy servers that require authentication either require a username and password to access the Internet or authenticate users by using their current domain credentials.

Depending on your proxy configuration, you may encounter one of the following problems when you use Windows Store apps:

You cannot install updates that are available in the Windows Store, and you may receive one of the following error messages:
- This app wasn't installed - view details.
- Something happened and this app couldn't be installed. Please try again. Error code: 0x8024401c
You cannot install new apps and may receive one of the following error messages:
- Your purchase couldn’t be completed. Something happened and your purchase can’t be completed.
- Something happened and this app couldn't be installed. Please try again. Error code: 0x8024401c
When you start the Windows Store app, you may receive the following error message:
- Your network proxy doesn’t work with the Windows Store. Contact your system administrator for more information.
Apps that are included with Windows 8 may indicate that you are not connected to the Internet. If you installed other apps from the Windows Store while you were connected to a different network, those apps may also indicate that you are not connected to the Internet. The apps may display one of the following error messages:
- There was a problem signing you in.
- You are not connected to the Internet.
Live Tiles for some apps may not update their content or may never show live content.
Windows Update may not check for updates or download updates, and you receive error code 8024401C or the following error messge:
- There was a problem checking for updates.

Resolution

Microsoft is aware of these issues, and we are investigating possible solutions. More information will be provided here when it is available.

You can reduce the effect of these issues by enabling unauthenticated access through your proxy server, preferably only for connections to URL addresses that are used by each app that is having a problem. Some proxy servers may suggest that you create an allow list (what they may call a "whitelist") of URL addresses.

To resolve these issues as they relate to using Windows Store apps or to using Microsoft apps that are included with Windows 8 or Windows Update, you can include the following addresses in an allow list on your proxy server and enable HTTP and HTTPS access to them:

login.live.com
account.live.com
clientconfig.passport.net
wustat.windows.com
*.windowsupdate.com
*.wns.windows.com
*.hotmail.com
*.outlook.com
*.microsoft.com
*.msftncsi.com/ncsi.txt

To resolve these issues with other apps, you may have to contact the application vendor for information about which URL addresses to include in your allow list.
