Microsoft ports network bug to all versions of Windows 10, fix coming next month

A week ago, on Patch Tuesday, Microsoft released Windows 10 cumulative update KB4480116 for  Windows 10 version 1809 (October 2018 Update) which ended up breaking the ability of Edge to download web pages on local networks from some devices, such as some router versions.

Microsoft acknowledged the issue, saying:

“After installing KB4480116, some users report that they cannot load a webpage in Microsoft Edge using a local IP address. Browsing fails or the webpage may become unresponsive.”

It turns out the issue is not exclusive to the October 2018 Update as KB4480976 (version 1803), KB4480967 (version 1709), and KB4480959 (version 1703), released a few days ago, brought the bug to the other versions of Windows 10 also.

It is likely the issue is related to fixing a serious vulnerability in Windows, and took priority over loading router web pages.

Microsoft is hoping to release a fix by next Patch Tuesday, but in the meantime, if you have to load (or another local network address) in Edge you can work around the issue by:

  • On the Security tab, select the Trusted Sites icon.
  • Select the “Sites” button.
  • Uncheck the box for “Server Verification Required” (https:\\ ) for all sites in this zone.
  • In the field “Add this website to the zone”, enter the local IP address that could not be loaded, eg
  • Select the “Add” button.
  • Select the Server Verification Required check box (https:\\  ) for all sites in this zone.
  • Select the Close button.
  • Select the OK button.
  • Restart Microsoft Edge.
