Something unexpected happened. Please contact your helpdesk.

Duo Mobile on iOS.

Please try the following steps to resolve the error.

• If you're on campus and connected to Wi-Fi, make sure you're connected to eduroam, and not umd-guest.
• If you're off campus and connected to Wi-Fi, temporarily disconnect from Wi-Fi and see if the issue occurs while using your device's cellular connection (if available).

If the steps above don't resolve the error, contact the IT Service Desk for additional assistance.
