[9.1.6] Issue with API - file upload doesn't work

Hey,

I am trying to upload file to GLPI using C# code, but every method I tried failed. After some googling I've found this project but even those CURL and php examples results in the same error: {"id":35,"message":"File /home/glpi-clean/public_html/files/_tmp/file.txt not found."} GLPI creates document, but file is not uploaded. I tried to copy document to the specified location manually and this does the trick, but obviously isn't a solution....

Another example with CURL: obraz

Do you have any ideas why it may not work? Maybe it's a configuration issue? I am running clear instance of GLPI (GLPI 9.1.6 ( => /home/glpi-clean/public_html)) created by our system admins.
