I finally wanted to switch from blender v.2.68 + Octane Server v.2.8 up to the latest Octane 2.0.
So I installed Blender_Octane 2.06 with Server v.6.5.
Everything works fine up to the point I want to load up any image texture to any slot.
In the attached example, the cube has only one material. In the diffuse slot an image texture is applied.
Suddenly the console says that it cannot load the image file to the server.
What am I doing wrong? The Node system has changed a lot since 1.20

Thanks for help.
