Description of Issue

Hello, my electricity network was interrupted and I had to restart my router and Roon on my Nucleus.
Since then I have an error message that my metadata optimization is paused.

How to restart or continue the metadata optimization?

Best Regards

Restart your Core once again, as that usually sorts it out.



This error message is typically displayed when the Roon Core can not reach Roon’s cloud servers.

I would recommend first reboot your router and any associated network equipment.

Then reboot the Roon Core and see if that fixes the issue.

Other have found updating use or for DNS services … see below …
