Hi,
Hope everything is going well.
1,Please check the smspxe.log on the server to see if there is any further information.
2.Check if all components like Boot images, OS-Images, Task-Sequences and Announcements are published to all distribution points in the Content Library.
3.Update the Network Driver to your Boot images. Then redistributed both updated boot images (x86 and x64) to the PXE-enabled DP and check if the redistribution succeeded.
Similar threads for your reference:

Feel free to contact me if you have any concerns/queries.
Best regards,
Simon
