Upload - Internal Server Error

[mikepiko]

Hi, i often get "Internal Server Error" Messages when uploading files to my printer.

When i try it multiple times (like 2 times in this example of the Log below) it works.

any idea what could go wrong ?

I got Mainsail 2.12.0 with Moonraker v0.9.3-0-g71f9e677 with Cura 5.8.1 and Cura2Moonraker 1.9.1 on my Voron Printer.

Thx
