Now it works. I think it mught be due to some kind of initialization problem. I just changed the preview pass to beauty before launching the preview, and now it always works, with any preview pass selected.
I could only reproduce it the very first time I tried.

It does it with just a default direct lighting template.
I go to shader AOV, change it to beauty render on Blender viewport is fine, when i initiate the octane viewport its not working.

It looks like it only happens the first time I launch the preview after loading your scene.
And only when Blender and the Server have been just launched.
Also, it doesn't happen 100% of the times here.
Did you try to close and reopen the Octane Viewport?

Sometimes it works, but without me doing anything just changing windows.etc.
But seriously for me it's 60% misbehaving.

There's something important to consider.
That viewport is there for debugging purpose; it shouldn't be used for "regular" work.
That said, we really need to be able to identify and track the exact steps to reproduce the issue for fixing it.
