 From your screenshot: iPXE is starting up with no problems, is 
successfully completing DHCP and downloading the file bootx64.efi as 
directed by your DHCP server.

This downloaded file is the UEFI shim, and the error messages you are 
seeing are coming from shim (not from iPXE):

   https://github.com/rhboot/shim/blob/main/pe.c#L264-L286

It appears that shim does not think that your next-stage binary is 
valid.  Unfortunately shim does not provide any information about what 
this next stage binary is (beyond the message "Fetching Netboot Image"), 
and so there is no further diagnostic information available in your 
screenshot.


Using shim's own netboot support in this way is strongly deprecated. 
Please instead use iPXE to load the kernel, initrd, and (if required) 
shim directly.  Documentation is available at

   https://ipxe.org/cmd/shim

Thanks,

Michael
