Windows Update 1809 (October update) is known to be problematic and was halted till a stable version of the update was launched. However, those who downloaded it already started facing issues, one of which was:
Check your connection, Error code is 0x80072EFD
This error prevents built-in apps like Microsoft Edge, Windows Store, etc from connecting to the network. While the error code is for Windows Store related issues, it has been in prominence after the 1809.
The cause behind this issue is that the client and Windows store is unable to connect. Obviously our first approach would be to check network connectivity in general. If the network connectivity is stable, try the following troubleshooting:
1] Disable the Firewall and anti-virus for the system and check if it helps. Here’s the procedure to disable Windows Defender Firewall.
2] Run the built-in troubleshooters. Go to Settings >> Updates and Security >> Troubleshoot. Select the Network Adapter and Internet Connections troubleshooters.
3] Check the date and time on the system. If they are wrong, correct the same.
4] Search for Disk Cleanup in Windows search and use that tool to delete temporary files.
Thereafter, proceed with the following solutions:
1] Registry level fix
2] Enable IPv6 for your system
3] Enable IPv6 for all Network Adapters through Windows PowerShell

5] Restart your system and check if it works now.
Solution 2] Enable IPv6 for your system
1] Press Win + R to open the Run window and type the command ncpa.cpl. Press Enter to open the Network connections window.
