This issue is typically related to Chrome Policies settings that prevent the Block Page from fully loading. A good indicator this is the root cause is if the Block Page loads without issue while browsing in Incognito Mode.

Resolving the Issue

Follow these troubleshooting steps to resolve the issue.

1. From Chrome's Settings, navigate to Privacy & Security and select Site Settings
2. Select JavaScript
3. Check the selection under Default behavior. Don't allow sites to use JavaScript is likely selected
   
   
4. If this is the case, add this key to the policy:
   HKLM:Software\Policies\Google\Chrome\BrowserSwitcherUrlGreylist
5. Add string values to the key so that each domain/url added gets a new string value

   1 = dnsfilter.com 
   2 = blockedv2.dnsfilter.com

Continue below if this is not the issue.

        "value": "${edge}"
