ROON NUCLEUS+ KEEPS CRASHING


Hello,  My Roon Nucleus+ is hardwired with cat 8 from my Verizon Modem.  I am then hardwired to two Roon endpoints.
I use a separate linear power supply for the Nucleus set to output 19v.
There is an internal hard drive installed and NAS connected.
Everything sounds great.

But my Nucleus+ is crashing now two or three times a day (becomes non responsive and my remotes can not find it.

I have tried rebooting the remotes, the endpoints and the router with no effect.

I must power off and back on the Nucleus for it to be ready and seen again.

Any help or thoughts appreciated!

You might also look at the M.2 SSD. If this is starting to fail, this will cause the Nucleus to crash. If you connect a monitor to the Nucleus when you boot it, the BIOS may give you some indication of a hardware problem. 

I had a problem with my Roon ROCK NUC which I initially built with a fairly cheap M.2 SSD. It was crashing once or twice a day. Sure enough, the BIOS was reporting problems.

When I replaced it with an Intel 660P M.2 drive, my NUC has been flawless. I have only had to reboot for software updates since then (last six months or so). 
Just because I am super suspicious of little devices, put a fan on it and see if this magically improves.
Might be a modem issue. If controllable by the user (you), check for software updates for the Verizon modem (and update). Otherwise, ask Verizon Tech Support to flash the modem.
Recently my Ayre DAC is no longer being recognized on ROON. I have contacted ROON and truth be told the person with whom I've been in email contact,
has been less than helpful/knowledgeable. I spoke with Ayre and they thought that a re set of the DAC  would fix the problem. It didn't. Thankfully I can speak with a life person at Ayre. FYI, ROON customer service personnel don't work on weekends. Good luck to us both.
