Same problem here. Several VLANs (deactivated master interface) result in "Change network from WIRED_NETWORK to NO_NETWORK".
EDIT: If I enable the master interface and wait until it configures a link-local-address (since there are no untagged frames on this interface) as 169.254.0.0/16 syncing works without any problems.
