C8 pro issue.. lose cloud connectivity on router reboot

there seems to be an issue with my c8 pro.. everytime my asus router reboots i lose cloud connectivity..

i just get "no response from hub"

there are no errors or warnings in the logs.
and ping and traceroute work from network test, in addition it also works with names so i have not lost dns as well..

reboot the hub fixes it everytime.. i am connected via dhcp to the router. no wifi enabled.

any ideas?

Wifi or Ethernet connection to your hub?

Ethernet
