Nucleus Not working, Can't access Web Interface
Unifi USG router, US 8 PoE 150W switch
Hey @Erik_Brunn1,
Thanks for writing in and sharing your report!
Could you bypass the switch and temporarily set up your Nucleus with a direct ethernet connection to your router, and see if you’re able to connect to the webUI afterwards?
It may be useful to review your router settings and check to see if your Nucleus is receiving an IP - that would be a good sign!
If you still can’t access the webUI, could you next plug a monitor into the Nucleus via HDMI, and power the device on (still connected to your router) and share a screenshot of what you see on screen?
We’ll be monitoring for your reply, thanks! 
I just got the web gui back after another hard power reset of the Nucleus. These issues started after a power outage and I’m thinking there might be possible corruption on the hard drive. Seems like the database is constantly rebuilding.
What would you suggest to start fresh or repair the Nucleus file system? We are going to make a backup of the clients music files on the internal storage first.
This is what I see on the drive currently. It’s almost like it started a new database? I can upload log files if needed as well. Currently the Mac OS Roon app is still adding in all the music from the Nucleus.
Hi, what should the recommended steps be going forward? Delete the old database and just continue on?
Hi @Erik_Brunn1,
Are you a dealer? If so, we do have a dedicated channel strictly for dealer support - contact dealersupport@roonlabs.com just for future reference. We’re happy to continue troubleshooting via this thread for this issue.
That would be helpful, please use the directions found here and send over a set of logs to our File Uploader.
Do you have a recently saved backup? If so, refreshing the Roon Server database may help. When viewing the webUI, are you able to review the percentage available under ‘Roon Sever Database’?
We’ll be on standby for a set of Nucleus logs - that should help indicate any hardware or database-related issues. Thank you!
