These errors were occurring specifically when accessing applications using Microsoft Entra and Duo as the MFA provider. Duo engineering was alerted to the issues via monitoring at 9:15 AM and promptly began investigating various factors that could have caused this error to occur, including checking the health of the different third-party services involved. Finally, the root cause was identified to be increased CPU usage resulting from a code change that added additional validation for security operations. The incident was remediated by scaling the backend services that support this integration.

This resulted in user sessions not being properly initialized, prompting the system to mistakenly identify these sessions as expired. Affected users were unable to complete enrollment and saw the message: “Your session has expired. Please try again.” The issue only affected enrollment flows using the legacy Traditional Prompt. Customers were able to successfully enroll by switching to the Universal Prompt enrollment experience as a workaround. Duo identified and corrected the issue by ensuring sessions are fully initialized before they arhttps://stspg.io/wv8bv5ypbr1yduo-security:2026-01-22T13:36:01.034-05:00Thu, 22 Jan 2026 18:36:01 +0000The issue causing authentication failures on our DUO4 deployment has been resolved.https://stspg.io/nb6y4p5qz2r5duo-security:2026-01-21T16:38:23.000-05:00Wed, 21 Jan 2026 21:38:23 +0000We have identified the cause of the issue for authentication failures with newly created MSP Sub-accounts on all our deployments and remediation steps have been applied to correct this.
