Could not boot: HTTP 5xx Server Error

[GlaDio]

Hello,

I am currently configuring a Synology NAS as an image storage server for my images.

I have configured everything necessary on the Synology NAS server (image folder, permissions, etc.).

I then configured a new Node on the web page with the IP address of the NAS server and with all the configurations.

When I try to boot in PXE to register a new host, I receive the following error:

http://192.168.42.233/fog/service/ipxe/boot.php… HTTP 5xx Server Error (https://ipxe.org/1d0c6598)
Could not boot: HTTP 5xx Server Error (https://ipxe.org/1d0c6598)
Chainloading failed, hit ‘s’ for the ipxe shell; reboot in 10 seconds
I think this is due to an error in my NAS configuration because when I want to register a host without my NAS server, everything works fine and I can even deploy and capture. I just don’t understand why I have an HTTP error.

Notes:

IP of NAS server: 192.168.42.252
IP of Fog Project server: 192.168.42.233
I would appreciate any help you can provide.

Thank you,
