i have had a running ignite server for 2 years, it suddenly getting an error and i cant get it to boot. I have checked tftp and it works, the nbp.efi is configured... but i am still getting  the following errors

 

Retrieving File Size
PXE-E18: Timeout.  Server did not respond.
Exit status code: Invalid Parameter

 

please let me know if anyone has any ideas or what to check next.

thanks
