**Core Machine (Operating system/System info/Roon build number)**  
Nucleus, OS Version 1.0 (build 227) stable  
Roon Server Software Version 1.7 (build 610) stable  
Roon Labs oftware, Version 1.0 (build 12) stable.

**Network Details (Including networking gear model/manufacturer and if on WiFi/Ethernet)**  
Nucleus connected via Ethernet Hub to Eero

**Audio Devices (Specify what device you’re using and its connection type - USB/HDMI/etc.)**  
Connected to Marantz SR5014 via HDMI

**Description Of Issue**

1. Roon recognizes Nucleus Core in network
2. Click on “connect”
3. Log-in screen appearing, I enter log-in credentials email and password  
(Note: Both correct when logging into roonlabs in browser, same network via wifi)
4. Roon replies “network error:please check your internet connection”
5. However, I can reach the roon nucleus admin page via IP in the browser via wifi - here it works

What can the issue be? Hub works fine as Nucleus can be found by scan and admin page can be opened via browser. So I exclude the hub and the cable.

Can you please check resp. run logs?

Hi @Norman_Stuertz,

Do you know what DNS your network is using? If you try Google or Cloudflare DNS is there any change?

Hi Dylan,  
Step 1: I did set the eero Router back to the Standard DNS Settings.  
Step 2: I rebooted Nucleus via the WebAdmin Interface  
Step 3: Restarted iOS app, chose Nucleus and entered credentials  
Result: log—in now works  
Resolved  
Thank you very much  
Kind regards  
Norman
