Troubleshooting SM Clients that Fail to Check-in to Dashboard

This article provides some basic troubleshooting steps for SM-enrolled devices that fail to check into Dashboard.

For all platforms, please verify that you've already configured your firewall per this knowledge base article: Configuring your Firewall for Meraki devices to communicate with the Meraki cloud

Devices cannot communicate with Dashboard when a proxy server is in use.

Windows

Does the device have an Internet connection?
Open up your task manager and see if m_agent_service.exe is currently running. If it has stopped responding, you can restart it by doing the following:
1. Open up the Run window and type in services.msc
2. Look for a service called "Meraki Systems Manager Agent" and start/restart it.
3. Ensure that the service is set to "Startup Type: Automatic".
Check the agent log file (for Agent ≤ 3.6.0, logging is saved to C:\Windows\Temp, for agent ≥ 3.7.0 logging is saved to: C:\ProgramData\Meraki\Systems Manager Agent\Logs). There should be several log files in that directory that start with m_agent_service. This log file may provide context for why the agent cannot check in. For more information see Windows Logging and Troubleshooting.

Is your device connected to a stable internet connection?
Is the device online and unlocked from any passcodes during 'force check-in'?
Look in Settings > General > Device Management. Are the Meraki Management and any additional configured profiles listed there? If so, does the Meraki Management profile description accurately reflect that of your Systems Manager dashboard network name?
Install Apple Configurator to a workstation, plug in the iOS device via USB, and look at the console output of the device. You should see events in the output that start with "mdm".
