My Directory structure looks like this:
/srv/exports/leboot

Can you paste the contents of this folder (ie. ls -la /srv/exports/leboot)? Also /srv/exports/29b116bf?

I've tested the latest #0322 build, netbooting an RPi3 and that works as expected, but unfortunately my pre-production RPi3+ doesn't appear to have netboot support so I can't confirm that is working (although, unless there's something wrong with Pi3+ bootcode I'd expect a production board to work, and chances are there's a misconfiguration with your server, eg. all files must be owned by root).     

 this is the content of /srv/exports/leboot:

Code:

/srv/exports/29b116bf has the same content, because it's a link to /srv/exports/leboot
(I configured a raspi3b about 6 month ago also for pxe network booting and this worked well! but at the moment i have only a 2b and a 3b+ available / i can est it with a 2b and an sd card only with bootcode.bin if this will help?!)

Update:
A Raspi2b with an micro-sd card only with bootcode.bin works out of the box after i created the symlink to the serial number!

Update2:
Can it be a network problem after PXE network boot? because i will not see a dhcp request from the the OS (Linux)! with my raspi2b i see the following:

Code:

the log before is the same.
