Thanks for writing in and sharing your report - welcome to the community! We’re excited to have you here, but we apologize in that its an issue that prompted your recent post.
Digging right in - we’ll need a bit more information around your Roon ecosystem and your network setup. How is your NAS connected to your router specifically, as well as your EVO running Roon Server?
Can you temporarily bypass your network switch, and see if you run into the same issue?
With that, can you reproduce the issue and share a more specific date and time?
I’d also review this KB article to ensure proper share settings are enabled on the NAS itself:
Some third-party firmware may provide their own means of connecting network shares (outside of Roon). Furthermore it might just be that the firmware is very outdated on your server and that is why you can’t successfully connect. Did you consult the 432 Evo manual or customer support already?
I noticed that you have no username/password set there, I have yet to see a NAS with no user/pass before, are you able to double check your NAS account settings (or try to make a new account)? Usually you’ll also want to enable “Windows File Sharing” on the NAS side if that option is available. One final suggestion would to also try using IP address instead of hostname, I’ve sometimes seen Hostname be unreliable. Let us know if this helps!
