FCPX - Storage Location No Longer Available

When we edit from our Synology 1821+ we get this error:

The storage location for one or more libraries is no longer available. The libraries will be closed so that no work is lost.

We are on M2 Mac Minis with 2.5Gb Ethernet adapters plugged into USBC into a 2.5Gb/10Gb Moker switch. The 1821+ is connected to the 10Gb port. We have 32GB of RAM, 4TB SSD Cache, eight 12TB IronWolf HD.

Is there some setting we need to change? We also recently followed this article from apple on how to “Use shared storage with Final Cut Pro”

But we keep getting this error.

Any thoughts on what might cause this?

Thank you!
