# MDM - Scanning time out

## Problem

You are trying to scan a mobile device or execute security commands like corporate wipe, remote wipe, lock the device, clear passcode, etc., and you get an error message "Scanning time out".

## Cause

While you scan your mobile device, or while trying to execute a security command, the scanning session might time out due to the following reasons:

- Connectivity issues between APNs and the managed mobile device
- Connection issues between the mobile device and the Endpoint Central server

## Resolution

Ensure that the managed device is always reachable through the internet. In case of lack of network connectivity, the APNs will not be able to reach the managed mobile device or the device might not be able to reach the Endpoint Central Server. This might cause a delay in response and result in session time out issues.
