The October 2018 Update is preventing modern apps from connecting to the internet for some [Update]

Microsoft's latest feature update for Windows 10 may have been a little too rushed. Since its release, users have encountered a host of bugs relating to Task Manager, Intel drivers and more; some users have even seen their data deleted after the update.

The newest bug encountered by users is a lack of connectivity in some apps following the update. A report on Microsoft's support forums shows users complaining about Edge, Mail, Calendar, and News being unable to connect to the internet.

One user writes:

After installing the Windows 10 October 2018 update (version 1809), Microsoft Store apps are no longer able to connect to the Internet. For example, Microsoft Edge is unable to connect to any websites, displaying the message, “Hmmm...can’t reach this page.” Apps like Mail, Calendar, and News are not working properly. And Microsoft Store says to check my connection.

Non-Store apps, such as Internet Explorer, are still able to connect to the Internet.

Microsoft has since confirmed that it is an issue that the company is aware of, and working on fixing. A Microsoft employee stated that the problem only affects users who have IPv6 disabled. While the company works on a fix, users are recommended to circumvent the problem by enabling IPv6 in their network settings as follows:

Open the Settings app and select Networking & Internet > Network and Sharing Center.

Select the network adapter you're using (by clicking the appropriate link next to “Connections”) and select Properties.

On the Networking tab, select the checkbox next to Internet Version 6 (TCP/IPv6).

Select OK to save your changes.

As our own Rich Woods explains, the company's changes to how it propagates Windows releases earlier this year may be causing undue strain and could be part of why both the April and the October 2018 updates experienced such early pains. That the company decided to entirely skip the Release Preview ring this time around probably didn't help matters, either.

Update: It seems network profile settings may be an additional factor causing the connectivity issues, even if IPv6 is enabled. A subsequent response by another Microsoft employee on the support thread offers the following solution if you're still experiencing issues after IPv6 is enabled:

If you still having issues after enabling IPv6, I suggest changing your network profile to Public. Go to Settings, Network & Internet and click on Change connection properties. Under Network profile, click on Public.

If that doesn’t work, run Network reset. This will reinstall your network adapters and set other networking components back to their original settings. You might need to reinstall any VPN software or virtual switches after. Go to Settings, Network & Internet and click on Network reset. Click on Reset now.
