Cannot load WebUI config.: MQTT RPC request timed out MqttTimeoutError

Добрый день , после обновления не грузится Config, MQTT Channels. Пишет:
Cannot load WebUI config.: MQTT RPC request timed out MqttTimeoutError

Здравствуйте! А остальные страницы конфигурации загружаются? Вероятно, не работает какой-то из служебных сервисов. Покажите вывод команды в командой строке Linux:

systemctl list-units --type=service

Должен быть выведен список всех загруженных сервисов и статус их работы.
Дополните, пожалуйста, тему информацией о версии контроллера, что было сделано и т. п., как указано в приветственном сообщении:
Добро пожаловать на портал техподдержки Wiren Board!

Контроллер HW 6.6.0
Обновление командой

apt update && apt dist-upgrade

выполнил 2 раза, на все вопросы замены измененных локально конфигурационных файлов , отвечал оставить

А остальные страницы конфигурации загружаются? - Configs - нет, MQTT Cannels - нет, WebUI, system,access level - да

Пришлите, пожалуйста, вывод команды systemctl list-units --type=service полностью, сервисов должно быть больше (перелистните страницу отображения вывода команды). Обратите внимание на работу сервиса wb-mqtt-confed.
Отдельно его статус можно посмотреть так:

systemctl status wb-mqtt-confed

Попробуйте перезагрузить контроллер.

Действительно перезагрузка второй раз помогла. Спасибо!

Wiren Board 6.6.0, release wb-2108

точно так же обновлялся со старой версии, выпущенно еще в начале этого года с помощью

apt update && apt dist-upgrade

после обновления перестали грузиться те же страницы в chrome и ff последних версий. В консоли бразуреа ошибок нет. Вывод systemctl list-units --type=service
