Troubleshooting Duo Push notification issues on iOS devices

Troubleshooting Duo Push Notification Issues on iOS

Quick Overview
  • This guide helps resolve issues receiving Duo push notifications on iPhone or iPad
  • Start with pull-to-refresh inside the Duo Mobile app
  • Most issues are related to notification or network settings

If you are not receiving Duo push notifications on your iOS device, follow the steps below in order. Most issues can be resolved without reinstalling the app or contacting the Help Desk.

Step 1: Use Pull-to-Refresh in Duo Mobile

Open the Duo Mobile app and pull down on the screen to manually check for pending login requests.

Pull to refresh in Duo Mobile

Pull-to-refresh forces Duo Mobile to check directly with Duo servers and is the most reliable way to confirm whether the app and account are functioning correctly.

If Pull-to-Refresh Works

If you can approve a login after pulling to refresh, but you do not receive push notifications automatically, the issue is usually related to notification settings.

Most common cause:
Notifications are disabled or restricted for Duo Mobile.

Check notification settings:

  1. Open Settings on your iPhone or iPad
  2. Scroll down and select Duo Mobile
  3. Tap Notifications
  4. Enable Allow Notifications
  5. Turn notifications off, then back on, to refresh the setting
  6. Fully close Duo Mobile and reopen the app

Check Network and VPN Settings

Push notifications rely on Apple notification services and can be disrupted by network changes.

  • Toggle Airplane Mode on, wait 10 seconds, then turn it off
  • Switch between Wi-Fi and cellular data
  • Restart your device

If you use a VPN, temporarily disable it and test again. Some VPN configurations interfere with push delivery.

If you experience issues while connected to Wi-Fi, try disabling Wi-Fi Assist:

  • Go to Settings > Cellular
  • Scroll down and turn off Wi-Fi Assist

If Pull-to-Refresh Does Not Work

If pull-to-refresh does not show pending requests, the Duo account on your device may need to be reactivated.

  • Confirm your device date and time are set automatically under Settings > General > Date & Time
  • If issues persist, reactivate Duo Mobile using the self-service portal

Follow the instructions in Managing Your Devices in Duo to reactivate your device.

Important:
Duo push notifications are only used for Duo-protected SFA applications. Third-party accounts use passcodes and do not send push notifications.
