Turn off the cabinet from the mains power plug for one minutes, then turn it back on.
If you have a cellular modem connected to your Keymaster instead of an internal network, please restart your cellular modem as well.
Once the cabinet has rebooted, run a network diagnosis test via Setup > Networking > Diagnostic to see if it was successful.
NOTE: If you have a cellular modem-connected Keymaster and the network diagnosis failed, please report back the lights flashing / solid on the modem, along with a photo of the back of it.
If the issue still persists, please contact the Smartrak Service Desk (For more info, refer to Service Desk).
