VMware Cloud Director is not recognizing the portgroups as valid OvDC Networks.
1. Remove the problematic networks from the VM via vCenter.
2. Delete the OvDC Networks in VMware Cloud Director for this OvDC.
3. Delete the Portgroups for these OvDC Networks in vCenter.
4. Re-Create the Portgroups in vCenter and the OvDC Networks in VMware Cloud Director.
5. Reconnect the VM nics to the correct networks.
This can occur if the portgroups are migrated from another vCenter Server.
