All Deployments: Duo Enrollment URL Session Expired Errors
Resolved - The issue causing enrollment failures that display the error message "Your session has expired. Please try again." has been resolved.
Feb 4, 20:11 EST
Monitoring - We have implemented a fix for the enrollment failures that caused the error message "Your session has expired. Please try again." and are monitoring the results closely.
Feb 4, 19:56 EST
Identified - We have Identified the cause of enrollment failures that display the error message "Your session has expired. Please try again." and are working to correct the issue as soon as possible.

As a workaround:
-If using enrollment email links, update the enrollment experience settings (https://duo.com/docs/administration-settings#enrollment) to show New Universal Prompt.
-If enrolling using in-line self enrollment with an existing application (https://duo.com/docs/enrolling-users#inline-self-enrollment), update that application to use the Universal Prompt (https://duo.com/docs/universal-prompt-update-guide).
-You can also enroll users manually from the Duo Admin Panel (https://duo.com/docs/administration-devices#adding-a-2fa-device-to-a-user) or issue an enrollment code for self-enrollment (https://duo.com/docs/enrolling-users#generate-enrollment-codes-for-existing-users).
