When using QS software with Multicast on a Windows system that has multiple IP addresses set statically on a single network adapted the multicast scan will fail the status test.
This can be resolved by removing additional IP addresses from the network adapter configuration. (Not a good fix since those are needed)
This issue only comes into play when extraction is needed however it also is faster on upload using multicast.
QS software should evaluate all IP addresses assigned to an adapter for subnet conflicts before reporting a multicast failure.
Does Lutron have intentions of fixing this issue in any future releases
