Is the Roon/Rock showing up in the Synology Router (is it getting an IP address successfully)?
If no, can you connect a monitor to the HDMI on the NUC then reboot and see what happens?
If yes, Are the devices you are trying to connect to the Roon/Rock on the same subnet? Subnet is the first three numbers of the IP address (192.168.1.xx for example).

What devices have you tried to use to connect to the Rock. Which devices specifically are you having issues with?

The more information you can give the better for assistance.

I was about to reply but was checking a few more things before doing so. My NUC was not able to be found despite disconnecting it from power. After shutting it down (it was very warm to the touch) and letting it cool for ~10 minutes, I plugged it in and Roon can back to life.

Strange, I’ve had this NUC for a few years and never experienced this behavior before.

All is well, thanks!

Is the NUC still in its original case? If so, it may be that there is a build up of dust in the fan assembly which is preventing the airflow when the fan turns on. This might not normally be a problem because, during normal Roon operation, the fan does not turn on. However, if being asked to do more intensive tasks like analyzing newly added content or even doing heavy DSP work, without the fan cooling working correctly, the processor may get too hot.

If this is the case, then there is no way to restore normal fan operation except by disassembling the NUC in order to be able to access the fan assembly and the cooling fins (which may be blocked). You may be able to clean the fan assembly without separating the NUC board and the fan assembly. However, you may have to separate them - in which case you will need to clean the top surface of the processor and the heat sink with isopropyl alcohol (or similar) and, on re-assembly, apply a thin layer of a new good quality thermal paste (I use Arctic MX-4). Unless you are very confident, don’t opt for one of the many ‘liquid metal’ thermal pastes. They are much more difficult to apply and the consequences of getting it slightly wrong can be much more serious since these pastes are electrically conductive (whereas the traditional pastes like MX-4 are not).

If your NUC is more than 5 or so years old, it is probably a good idea to replace the thermal paste anyway because it starts to loose its effectiveness after that.

At the beginning of the year, I transplanted my NUC board into a new (fanless) case and, in doing so, found that, even after just 20 months of operation from new, the airflow through the fan assembly had been seriously compromised by the build up of dust.
