NFS and SSH clients disconnected and dietpi is crashing

Hi,

I enabled NFS on DietPi (running on rockpro64) and when from my macbook I access the dietpi box, then after a few seconds the NFS client is disconnected. More surprisingly, the SSH is also crashing. Next, I cannot anymore access the box using SSH and I must reboot.

ssh root@dietpi.local
ssh: connect to host dietpi.local port 22: Connection refused

Question: How can I investigate the problem (log, …) and fix that ?

Cheers

Charles

Forget this thread as I did a mistake as 2 machines have the same IP address within my network
