A cloud-based identity and access management service for securing user authentication and resource access
Hello Derek Foo,
Thank you for sharing the details and screenshot. The error “Unable to complete due to service connection error” when accessing Security > Permissions in Enterprise Applications usually indicates a portal connectivity issue rather than a permissions problem.
Please try the following steps:
1.Try another browser / InPrivate window this rules out cached tokens causing the service connection failure.
2.Disable Browser Extensions Ad blockers or privacy extensions may interfere with Microsoft Graph calls.
3.Alternative Method to Grant Consent If the portal still fails, you can grant tenant-wide admin consent via App Registrations:
- Navigate to Microsoft Entra admin center → App registrations → Select the app → API permissions → Click Grant admin consent for .
Try using Microsoft Graph PowerShell to grant the admin consent instead of the Azure portal:
Connect-MgGraph -Scopes "Application.ReadWrite.All"
Grant-MgOauth2PermissionGrant -ClientId <AppId> -ConsentType AllPrincipals
Replace <APP_ID> with your application’s ID.
