Failed to Download Certificate Files

This article reviews what it means when your D2 WiFIRE grill throws the notification, Failed to Download Certificate Files, when attempting to download a firmware update.

What Does 'Failed to Download Certificate Files' Mean?

If you get an error on your grill saying, "Failed to Download Certificate Files," this means that the grill errored out while obtaining the certificates needed to migrate over to the newest firmware version. Not to worry; following some of the troubleshooting steps below should get you back grilling. 

How to Resolve a 'Failed to Download Certificate Files' Alert

1. Confirm that your grill is still connected to WiFi.
   • Chances are that your signal is weak where your grill is located or perhaps your WiFi connection was interrupted.
2. Find your grill's firmware version (Menu > Settings > About Grill) and proceed. Next steps will depend on which firmware your grill is on currently.

   • Android: Varies with device brand, but typically found in the Device Settings or App Settings menu.
