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:
The AD FS Token-Signing certificate is not valid until {0}.
Note This log is located at Admin_Applications\SSO_Diagnostic_Tests\ADFSDiagnostic.txt.

Additionally, when you sign in to your Microsoft cloud service such as Office 365, Microsoft Azure, or Windows Intune by using a federated account, you may receive a "There was a problem accessing this site" error message before you can provide your credentials to AD FS.


This issue may occur if one of the following conditions is true:
  • There is an on-premises time issue is that's causing authentication problems.
  • The AD FS token-signing certificate is expired because AD FS certificate auto-renew is deactivated.


To resolve this issue, use one of the following methods, as appropriate for your situation.

Method 1: Troubleshoot on-premises time issues

To resolve on-premises time issues that are causing the single sign-on (SSO) authentication failure, see the following Microsoft Knowledge Base article:

2578667 "Sorry, but we're having trouble signing you in" and "80045C06" error when a federated user tries to sign in to Office 365, Azure, or Windows Intune

Method 2: Reissue the token-signing certificate

To reissue the token-signing certificate, see the following Microsoft Knowledge Base article:

2713898 "There was a problem accessing the site" error from AD FS when a federated user signs in to Office 365, Azure, or Windows Intune
