iPXE HTTP 5xx Server Error - Could not boot

[Taspharel]

Hi everyone.

Have been using FOG for quite some time and everything was great.

We are running FOG 1.5.7.102. Kernels Up to date (I think 101 is the latest?)

Today I suddenly got the message:

http://192.168.43.17/fog/service/ipxe/boot.php... HTTP 5xx Server Error

Nothing has changed in our setup as far as I am aware.

Httpd Error Logs last entry is:

PHP Logs last Entrys are from a day ago, … only NOTICE: [pool www] child {number} started messages

Anybody can give me a hint?

Thanks so much.

Aaaaand… stupid me.

Sorry for bothering you.
