Restore Advanced Internet Settings and Disable Proxy
Resetting your Windows internet configurations and disabling unnecessary proxy servers can resolve DNS and network blocks.
Network errors on Windows are often caused by misconfigured proxy settings or corrupted temporary network configurations. Resetting the Internet Options clears these bad configurations and allows your browser to reach the Microsoft servers.
Search for Control Panel in the Windows search bar, navigate to Network and Internet, and click on Internet Options.
Go to the Advanced tab, click the 'Restore advanced settings' button, and then click Apply to save the changes.
Switch to the Connections tab and click on the 'LAN settings' button near the bottom of the window.
Check the box for 'Automatically detect settings' and ensure the box under Proxy server is unchecked. Click OK to save.
Open a Microsoft Edge InPrivate window (or your preferred browser's incognito mode) and try accessing the site again.

Frequently Asked Questions
What causes the 'server IP address cannot be found' error?
This error occurs when your Domain Name System (DNS) fails to resolve the website's URL into an IP address. It can be triggered by poor internet connectivity, corrupted DNS cache, or misconfigured proxy settings.
How can I flush my DNS cache on Windows?
You can clear your DNS cache by opening the Command Prompt as an administrator, typing 'ipconfig /flushdns', and pressing Enter. This often resolves localized domain resolution failures.
Why does the site work on other devices but not my current PC?
If the error is isolated to one computer, the issue is likely rooted in that device's specific network settings, proxy configurations, or an outdated browser cache, rather than a Microsoft server outage.
