Thanks for reaching out. Based on your description, as mentioned by @BlackJack it looks like Windows is blocking access to the Nucleus/ROCK internal storage due to its security settings regarding “Guest” access.
This is a common behavior in recent Windows updates (10/11), where the system automatically blocks network shares that don’t require a password. Since Nucleus is designed to be accessible without a password for convenience, Windows essentially puts up a barrier.
We have a step-by-step guide on how to adjust this setting in Windows so you can copy your music files:
Please give those steps a try and let me know if you are able to connect afterwards!
It’s been some time since we last heard from you, and I just wanted to check in to see if you were able to solve the issue you were experiencing. If you still need assistance or have any further questions, feel free to reach out. We’re here to help!
