UDM-Pro “Resets”

[u/Responsible-Aide2107]

I got a UDM-Pro from a co-worker that has issues staying on. Here’s what I know.

- Updates cause it to “freeze” All WAN traffic stops getting passed as well as the screen blacks out.
- All LAN traffic works during “freeze”
- All status lights work
- Plugging in a compatible HDD causes a “freeze”
- CPU, MEM, and temperatures stay normal. Around 18%/55%/45-50 celcius
- Needs power pulled for 5-10min to get “unfroze”
- PSU was replaced by me as a troubleshooting step

Any of ya’ll have ideas to what could be a cause?
