Troubleshooting
Start with pgpu doctor; it names most problems and their fix.
The phone can’t reach the machine
Check the agent is running with pgpu. If doctor says UDP is blocked, the connection goes through a relay and still works, a little slower.
No GPU stats
Run nvidia-smi. If it fails, reinstall the NVIDIA driver. In Docker, start the container with --gpus all.
The agent refuses to start
It refuses root. Run it as your normal user, or inside a container.
