Jetso Orin NX 36.4.3 QSPI reported an error while burning

QSPI reported an error while burning.
May I ask what the reason is?

Flash failure
Either the device cannot mount the NFS server on the host or a flash command has failed. Check your network setting (VPN, firewall,…) to make sure the device can mount NFS server.

Cleaning up…
