Issue: While trying to open a whitelisted URL using Internet Explorer or Microsoft Edge, the URL does not open.
Solution: The whitelisted URL may be blocked by network isolation, an application security feature in Windows that restricts certain types of network communication. You can disable this restriction by enabling loopback for network access, allowing you to open the URL in the browser.
Caution: Enabling loopback is intended only for development or debugging purposes. Consult Microsoft’s documentation on enabling loopback and troubleshooting network isolation before performing any commands that disable security features in your environment.
To enable loopback, perform the following command using PowerShell and with elevated privileges or Administrator rights:
CheckNetIsolation LoopbackExempt -a -n="Microsoft.Microsoft-Edge_8wekyb3d8bbwe"
