Hi, 

Reason 8 is BLE_HCI_CONNECTION_TIMEOUT (Connection Timeout).

Could you capture a sniffer log?

If you have extra DK or dongle, you can use nRF Sniffer: https://www.nordicsemi.com/Products/Development-tools/nRF-Sniffer-for-Bluetooth-LE

Not sure the fast advertising after connection causes the issue or not. Good to also check it. 

Regards,
Amanda
