This is all I see on boot:

resolv.conf has no nameserver:
# cat /etc/resolv.conf ### Autogenerated by VyOS ### ### Do not edit, your changes will get overwritten ### # name server from static configuration search home
Even if I try to renew or release the dhcp lease, the result is the same.
Edited: removed reference to T2409 as it's unlikely the cause and has been merged to current.
