Bluetooth not working anymore?

Has Bluetooth stopped working? Suddenly none of my BT devices gets updated, and I can find the following in the log:

Logger: homeassistant.components.bluetooth_tracker.device_tracker
Source: components/bluetooth_tracker/
Integration: bluetooth_tracker (documentation, issues)
First occurred: 11:13:59 AM (78 occurrences)

Error looking up Bluetooth device
Traceback (most recent call last):

    results = _bt.hci_inquiry (sock, duration=duration, flush_cache=True,
_bluetooth.error: (110, 'Operation timed out')

During handling of the above exception, another exception occurred:

bluetooth.btcommon.BluetoothError: error communicating with local bluetooth adapter

Did you find a solution? I have the same error.

I have also the same error with the actual version 0.116.4
Did somebody find a solution?

Did you by any chance also update Operating System to 4.14. It broke Bluetooth for alot of people. If so downgrade to 4.13 again.
