Tips for Troubleshooting Duo

Here are some tips and tricks you can use to troubleshoot Duo issues.

Always recommend that you run the latest DUO app
Turn off Wi-Fi on your phone and turned it back on
Close Duo completely, as this seems to refresh the app
On iPhone - under DUO - there is a toggle for it to use the cellular network and not just the Wi-Fi network. This is necessary in order for Duo to work all the time.
Roaming set on - UCSD will send you the codes if you have the app open.
Most people use push notifications - so have to make sure they are set for Duo to send push notifications
Do not set your phone to silent as you will not get UCSD notifications or be aware of the setting and check for Duo notifications
Set permissions to allow for badges and notifications on your iPhone or if on another type of phone set the permissions correctly to allow notifications
Allow duo to send notifications when in do not disturb mode during work hours
