Unable to Receive Duo Push
When accessing a service a Duo push to your mobile device is never received. One cause could be network congestion or there could be mobile phone settings preventing the Duo mobile app from working correctly.
If the problem is related to your phone data settings, you may see the message below:
"A WiFi or cellular network connection is required. Please check your network settings."
Resolution / Next Steps
On Android devices:
Enable Background Data & Disable Data Saver for Duo Mobile
Make sure Duo Mobile is allowed to run freely over cellular:
- Go to Settings > Apps > Duo Mobile > Mobile data & Wi-Fi.
- Ensure Background data is ON and Unrestricted data usage is Enabled.
- Also, make sure Android’s Data Saver is off - or that Duo Mobile is marked as exempt. All of this ensures push messages aren’t getting blocked.
On Apple Devices:
Ensure the following settings are enabled:
- Background App Refresh
- Go to Settings > General > Background App Refresh.
- Make sure Background App Refresh is enabled globally, and specifically for Duo Mobile.
- Cellular Data Permissions
- Go to Settings > Cellular > Cellular Data.
- Scroll down and make sure Duo Mobile is allowed to use cellular data.
- Low Data Mode & Low Power Mode
- If Low Data Mode (under Wi-Fi or Cellular settings) or Low Power Mode (under Battery settings) is enabled, push notifications may be delayed or blocked. Turning these off can help.
- Notifications
- Go to Settings > Notifications > Duo Mobile.
- Ensure notifications are allowed - Duo uses Apple Push Notification Service (APNS), which must be permitted.
