In order to save battery life, some smartphones will stop an application from running under various conditions. If you open the Duo Mobile application on your device, you should receive the prompt within a few seconds.

You may have trouble receiving push requests if there are network issues between your phone and our service.

Many phones have trouble determining whether to use the Wi-Fi or cellular data channel when checking for push requests, and simply turning the phone to airplane mode and back to normal operating mode again often resolves these sort of issues, if there is a reliable internet connection available.

Similarly, the issue may be resolved by turning off the Wi-Fi connection on your device and using the cellular data connection.

Also, check the time and date on your phone and make sure they are correct. If the date and time on your phone are manually set, try changing your device's configuration to sync date and time automatically with the network.

If neither of these suggestions work, please contact the UT Service Desk at +1 512-475-9400 to request re-activation of Duo Mobile. You can log in with a pass code generated by the Duo Mobile app and send a new activation link to your phone. See Duo’s Managing Your Devices documentation for additional instructions.
