Does your device meet the requirements? Also you shouldn't need configurator if all of your devices are registered in ADE, if they aren't registered ask the reseller to enrol them for you.
Using ADE is much easier than mucking around with configurator.
Prerequisites
- Apple Configurator 2.5 or greater
- macOS 10.12.5 or greater
- iOS device(s) powered up and physically connected to Mac
- The Mac and iOS device(s) are not locked
- Internet access with unblocked access to Apple and Meraki Systems Manager
- Refer to Help > Firewall info for a list of ports and IP addresses
- For Automatic enrollment: iOS devices must be in Apple’s DEP program.
