Hmmm.....can't reach this page

The “Hmmm… can’t reach this page” message in Microsoft Edge on Windows 11 usually indicates a browser or network/security configuration issue. Based on similar Edge connectivity problems, use these targeted steps:

1. Test in InPrivate and clear Edge cache

• Open Edge and start an InPrivate window (Ctrl+Shift+N).
• Try the same links or sign-in pages.
• If they work in InPrivate, clear cached data in normal Edge:
  • In the Edge address bar, enter:
    • edge://settings/clearBrowserData
  • Choose All time and select at least Cached images and files, then Clear now.
• Close and reopen Edge and test again.

2. Check advanced TLS feature (if many sites fail) A misbehaving advanced TLS feature can cause many sites to fail to load.

• In Edge, go to edge://flags.
• Search for TLS.
• Locate 1.3 Post-Quantum Key Agreement.
• Set it to Disabled.
• Restart Edge and test the problematic sites again.

3. Verify general connectivity and other browsers

• Confirm that the same links open correctly in another browser (for example, Chrome).
• If they fail in all browsers, the issue is likely with the network (router, DNS, VPN, or security software) rather than Edge.

4. Reinstall Edge if it will not open or is badly corrupted If Edge itself is unstable or will not start reliably, reinstalling it on top of the existing installation can repair damaged components.

• Download the latest Edge installer from the official Microsoft Edge download page.
• Run the installer and allow it to reinstall Edge over the current version.
• Restart Windows and test links/sign-in again.

5. If the problem started after a Windows update

• Check Settings → Windows Update and ensure all pending updates are installed.
• Restart the PC at least once more after updates complete, as incomplete updates can cause odd browser behavior.

If the error persists after these steps, capture whether it happens on all sites or only specific ones, and whether it affects all browsers or only Edge; that distinction will point to either a system/network issue or an Edge-specific configuration problem.
