Could not mount image folder (/bin/fog.upload). mounting IP:/images/dev on /images failed: connection time out

[vanlam]

I set up a FOG server on Ubuntu 24.04 (Proxmox 8.3), I have captured and deployed images on Proxmox, everything worked fine. But when I deploy the image on a physical PC, it doesn’t work. I tried capturing packets with “tcpdump -ni any port 2049 or port 111”, but no packets on port 2049 are reaching the server at all.

pls help me!

@vanlam You may need to ensure the fog server at 192.168.13.99 is running NFS appropriately?

@Tom-Elliott yes, I checked the services, they all running.

I deployed the image using a VM on Proxmox and it worked, but with a phisical PC it gives the error like above. All are on the same VLAN.
