Random Reboots After Fresh HexOS Install on UGREEN DXP4800 Plus

[JUhalt]

Hi everyone,

I just completed a fresh install of HexOS on a UGREEN DXP4800 Plus, and I’m running into repeated, seemingly random reboots.

System specs:

• Intel Pentium Gold 8505 (5-core)

• 8 GB DDR5 RAM

• Built-in 128 GB SSD (used for the HexOS system install)

• 4 × 12 TB HDDs (data drives)

The installation itself appeared to complete successfully. The system boots and reaches the Console Setup screen (the menu with options 1–10), and it is assigned an IP address.

I’m able to access the web UI from my PC via https://deck.hexos.com, but after a short period the connection drops and I see a “server not available” / disconnected page. When I check the NAS physically, it appears to have rebooted on its own and is back at the Console Setup screen again.

This cycle keeps repeating: boot → console menu → brief web access → reboot.

At this point I’m not sure whether this is a hardware issue, a configuration problem, or something specific to the DXP4800 Plus platform. Any guidance on logs to check, settings to change, or known issues would be greatly appreciated.

Thanks in advance for the help!

Best
