How to Fix

To address the unexpected error you are encountering, you can follow these general troubleshooting steps:

1. Restart the System: Sometimes, a simple restart can resolve unexpected errors.
2. Check for Updates: Ensure that your system and any related software are up to date. Updates can fix bugs that may cause errors.
3. Review Logs: Look at the logs associated with the error, especially the Correlation ID and Timestamp you provided. This information can help identify the specific issue.
4. Configuration Review: If this error is related to a specific application or service, review its configuration settings to ensure everything is set up correctly.
5. Contact Support: If the issue persists, consider reaching out to Microsoft support or your IT department for further assistance.

These steps can help you identify and potentially resolve the unexpected error you are experiencing.

This error on ADFS usually means something failed internally and ADFS only returned a generic “unexpected error.”

The correlation ID and timestamp don’t point to a specific issue by themselves.

To actually fix it, you need to check the ADFS server logs.

The quickest way to troubleshoot:

1. Go to AD FS > Admin Event Logs on the ADFS server.
2. Look under Applications and Services Logs > AD FS > Admin at the exact timestamp you provided.
3. The matching event will show the real cause, usually one of these:
   • Token signing certificate expired
   • Service account password changed
   • Trust with the application is broken
   • Time sync issue on the ADFS server
   • Missing or invalid claim rule
   • TLS/SSL certificate problem

Once you find the matching event in the ADFS Admin log, it will clearly tell you what failed.

The correlation ID alone cannot be fixed without checking that server log.
