Need help with Roon, system output is not showing by Streamer/DAC

Sorry meant 192.168.1.1

It might be worthwhile to reboot your network equipment as well (modem, router, switches, etc.).  Once that is done and running, then reboot your Roon Core, Endpoints, etc.

Maybe do the following; 

• Restart Everything

Power cycle your Metrum Ambre, your iMac (Roon server), and your network router/switch. This often resolves network discovery issues.

• Check Network Connections

Make sure the Ambre is connected via Ethernet (not Wi-Fi) and the cable is secure.

• Verify Ambre is Powered On

Confirm the Ambre’s lights are on and it’s functioning.

• Roon Settings

In Roon, go to Settings > Audio and see if the Ambre appears under “Roon Ready” or “Networked” devices. If not, click the refresh button in that section.

• Disable VPNs/Firewalls

Ensure there are no VPNs or strict firewalls running on your iMac that could block Roon from seeing network devices.

• Check for Software Updates

Make sure both Roon and your Ambre are running the latest firmware/software.

• Multicast Routing

If you use a custom router, ensure “Enable Multicast Routing” is turned on in your router settings, as Roon needs this for device discovery.

• Reinstall Roon (if needed)

As a last resort, uninstall and reinstall Roon on your iMac. Sometimes a fresh install restores device visibility.

I hope this helps   

Have you gone into Roon's Settings > Audio to see if the Metrum is shown there and enabled?
