Hi Hean, I had seen a similar behavior with VMs deployed on shared network. The issue was that cloud-init first searches for the dhcp leases file, and only if it can't find one does cloud-init use the default gateway to reach the metadata server. So, firstly you may want to check for the presence of the dhclient lease file, which contains the parameter - 'dhcp-server-identifier' which would correspond to the VR IP. If it isn't present, you could try to acquire the lease by running ' dhclient -1' and then try resetting the password.
