Bluetooth больше не может обнаруживать устройства. 16.04.3

Bluetooth раньше работал, но по какой-то причине он отключается от наушников примерно через 5 минут после подключения. Я гуглил онлайн, пробовал кучу вещей, очищал / переустанавливал кучу вещей, и теперь Bluetooth даже не может найти мои наушники.
