Nvidia Sync connect fails with Connection Error

Hi!

Nvidia Sync issues a Connection Error - no route to host, when I try to add my DGX Spark. Same behavior with the .local hostname as with the IP. SSH in Terminal works with both. I am on a MacBook Pro. My colleague gets it connected with the same setup using the IP. Any ideas how to fix this?

Thanks,

Andreas

Can you share the output from the logs.
To get to the logs, click on the NVIDIA Sync icon, select the ellipsis (three dots), then click logs.
You want to pull from “NVIDIA Sync-desktop.log” and “nvsync.log”

Make sure you have the latest version: NVIDIA Sync — DGX Spark User Guide

can you validate you can ping the IP from your system?
I am seeing the message “Could not dial any address for 192.168.1.133:22"”

I can ping and ssh into the box from the command line …

ping spark-7028.local

A new version of NVIDIA Sync (0.47.0) is available. Can you update?

Have you ever connected from your system (Mac) to the DGX Spark before?
Is the Spark using WiFi or ethernet connectivity?
As you are pinging .local I am assuming you are on the same L2 network and no firewall/proxy in between?

The official download under https://workbench.download.nvidia.com/stable/nvidia-sync/latest/nvidia-sync.dmg is the same as I have already installed. Where can I get the new version?

Regarding you other questions:

  • I can connect to the DGX Spark within the terminal
  • The Spark is using WiFi
  • There is nothing between my Desktop and the Spark in terms of firewall/proxy

Does NVDIA-sync have local network access?

Settings → Privacy & Security → Local Network → NVIDIA-sync (should be on)

The App does not appear in the list.
