Nucleus Web Administration Interface
What is the Web Administration Interface
The Nucleus Web Administration Interface (the "Nucleus Web UI" for short) is a built-in control panel, accessible from any web browser on your network, that lets you manage your Nucleus at the system level. It works independently of the Roon app, so you can use it even when Roon isn't running or can't connect.
Connecting to the Web Administration Interface
The Nucleus Web Administration Interface can be accessed via the Roon app by navigating to Settings -> Setup -> Find Roon OS and then Find. On the new window showing all the available Roon OS devices, click on the Nucleus IP address. Doing so will open the Web Administration Interface:
For more details on how to load the Nucleus Web Administrative Interface through the Roon app, please, visit the Connecting to Nucleus guide.
Using the Web Administration Interface
The Web Administration Interface gives you access to system-level controls for your Nucleus, independent of the Roon app. From here you can:
Functions
- Reboot or power off: the red button at the top right can be used to reboot or power off the Nucleus.
- Reinstall RoonOS and RoonServer: the Reinstall button under the Operating System section will always reinstall the latest firmware available for the Nucleus, even if you are already running the latest one. This operation can take several minutes depending on your internet connection.
- Stop and Restart RoonServer: The drop-down button under the Roon Server Software section allows you stop/start or restart your Nucleus (Roon Server). Stopping Roon Server can be useful before doing a large import.
- Reset all Settings / Databases: Resetting all Nucleus settings, Roon settings, and your Roon database will restore the Nucleus back to "factory defaults".
- Format internal storage: if you install a hard disk drive (HDD) or solid state drive (SSD) in the Nucleus for music stoage, the drive must be formatted by Roon OS before it can be used, by clicking the "Format" button. More information on internal storage can be found here.
- Tailscale is an app that creates a private, secure connection between your phone and your Roon Server, making it easier to stay connected even when you're away from home. If you've been having trouble with ARC due to your internet provider or home network, Tailscale could be a great solution. Learn more here.
- Setting a static IP address: like most networked devices, the Nucleus defaults to DHCP for its network interface configuration. It is not generally required (or recommended) to use a static IP; however, when this action is required, please, follow the steps below
- To configure the interface manually, change the IP Address Setup to Static IP, then manually enter IP Address, Netmask, Gateway, and DNS Server.
Reinstalling the software will not affect your settings or your Roon Database. This will not make any changes to your internal storage (Nucleus Internal Storage). 
Note: Incorrect static IP settings could render your Nucleus unreachable on your network. A thorough understanding of networking principles and familiarity with the host network are strongly recommended if you intend to configure your network interface manually. - If you accidentally enter an incorrect static IP and your machine becomes unreachable, using a second network interface will help reconnect the device as it will be configured by default to use DHCP. Press "Save" when you are done.
Configuring a second network interface - If you use a USB network adapter with Nucleus, it will populate itself with a second network interface. This second interface will appear as a new tab under the Networking section and can be configured the same way as the onboard gigabit ethernet port.Related Articles
