I can play songs with the network disk, but I don't know if it can't connect after the upgrade.
Describe your network setup
Previously, three devices were able to operate normally, but now only one can connect, and the other two cannot connect, and there is a problem reading the folder.
Check the firewall(s) are allowing access* then, if they are correct, you could try removing the folders from storage, restart Roon server and then try adding them back.
*system updates can, on occasions, change firewall rules so it’s worth checking.
Thank you for reaching Roon support and welcome to our comunity !
I’ve gone ahead and enabled diagnostics mode for your account. This means that the next time your Roon Server is running, a set of logs will be automatically collected and uploaded to our servers for analysis.
Could you please confirm whether you’ve already tried restarting the Roon Server?
Additionally, if you remove the affected folder and re-add it, does the issue still persist?
