  • Error syncing with servers
  • Error syncing menu item inventory
  • Error syncing order with servers
  • Cannot sync to Toast cloud

If so, follow these steps to troubleshoot:

  1. Check if you’re restaurant has internet by following the steps here to Verify Your Internet Connection. With this article, you will check your Ethernet and Wi-Fi settings, and confirm connectivity. 
    • If your device is wireless and you have discovered your restaurant does not have Wi-Fi, contact your Internet Service Provider (ISP) for additional troubleshooting. 
    • If your device is hardwired, review the section in the article above titled Check Hardwired Device Connection. If you are properly connected to ethernet, proceed to step two below. 
  2. Check Toast System Status to see if Toast is experiencing an outage. Typically, a Toast service outage is marked by the error message Toast Service Disruption.
    • If there is a Toast outage, please review the information in Use Toast in Offline Mode.
    • If there are not outages, proceed to step three.
  3. Check Unsettled Credit Card Payments on Device.

    • If have pending payments and don’t mind losing them, proceed to step four. 
    • If you have pending payments and don’t want to lose them, please contact Customer Support for further assistance. 
  4. If you have no pending payments, you can perform various device resets:
    • Power cycle your Toast Flex by turning it off and/or unplugging the device. Wait at least 30 seconds, then plug in the device and/or turn it back on. To learn more, see Restart Your Device to Improve Performance.
    • Force quit the Toast App
    • Clear Cache
    • Resync all data

 

If there are unsettled or pending credit card payments that have not yet synced with Toast servers or are stuck on a device, resyncing all data or power cycling the device will cause those payments to be lost forever. Check your device for pending credit card payments of confirmation before resetting or deleting all data as those payments cannot be recovered if lost.
