Thank you for your reply. Your email was forwarded my way for further investigation.
This issue can also occur if your network interface card (NIC) doesn't have a unique MAC address. We've confirmed that this is the case with some Nvidia NICs, which appears to be the case with your MAC address based on your logs. Currently, a unique MAC address is required to authenticate computers used with the Music Manager.
For more information about your MAC address, please contact the
manufacturer of your NIC.
