Почему перестали ресолвиться сайты по DNS на Mikrotik Chateau LTE18 ax после добавления двух WAN?

Уважаемые эксперты Mikrotik, подскажите пожалуйста, что нужно исправить в конфиге Микротик - перестали открываться сайты по доменному имени на Mikrotik Chateau LTE18 ax после добавления двух WAN. При подключении к Микротик по wifi успешно пингуется адрес 8.8.8.8, но по имени домена сайты не открываются, похоже не работает DNS - не резолвится.

Через терминал самого Микротика пинг на ya.ru проходит, но при подключении по WiFi интернет на конечных устройствах ни один сайт не открывается по доменному имени. НО, пинг, например до 8.8.8.8 проходит! В чем может быть ошибка конфигурации?

Конфиг

Ошибку исправил, была конфликтующая запись вида:
/ip dhcp-server network
add address=192.168.1.0/24 comment=defconf dns-server=192.168.1.20 gateway=\
192.168.1.1 netmask=24
