After you run the Microsoft Online Services Diagnostics and Logging (MOSDAL) Support Toolkit, the Active Directory Federation Services (AD FS) diagnostics log shows the following error message:
The Microsoft Office 365 Authentication System login URL could not be accessed
Note This log is located at Admin_Applications\SSO_Diagnostic_Tests\ADFSDiagnostic.txt.

Additionally, you may notice that the client computer's Internet browser can't load the webpage when you sign in to your Microsoft cloud service such as Office 365, Microsoft Azure, or Windows Intune by using a federated account.


This issue may occur if network problems are limiting access to the cloud service.


To resolve this issue, follow the steps that are described in the following article in the Microsoft Knowledge Base:
