Error at starting command UNC path

Hy there,

I sucessfully installed and configured OCS Server 2.3.1 with Windows Agent 2.3.0.

Package Deployment is working flawless with one exception:

I´m trying to execute a setup file for VRED 2018 wich is located at a network location.

Here are the logs:

If I excute this command manually (\\192.168.XXX.XXX\deployment\vred2018u1\Img\Setup.exe /qb /I \\192.168.XXX.XXX\deployment\vred2018u1\Img\VRED2018U1.ini /Trial /language en-US) in a cmd it´s working.

Can OCS handle UNC-Paths? Are there any other log files I could consult? Maybe on the server side (Linux)?

Any help is much appreciated!

Greetings
