The Nucleus HDMI output can provide very useful diagnostic information. This process will involve connecting the Nucleus via HDMI to a TV or monitor and then checking to see what is being displayed.
· Yes, I am willing to try the HDMI test
When you plug in the HDMI cable to the TV or Monitor, is there something being displayed on the screen?
· true
On the Nucleus HDMI output, what do you see?
· "Roon OS Web UI can be directly accessed at [https://xxx.xxx.xxx.xxx/](https://xxx.xxx.xxx.xxx/)" and the address is NOT http://169.254.XX.YY/
In the Roon app, please try to click on the "Select a different Roon Server" button. Are you able to reconnect to Nucleus from the list?
