Are you using our tutorials to set up the server? Or is everything just at defaults? As a pure guess I’m wondering about permissions between your desktop, that file and the server.
Have you tried other Upload methods? If those work/don’t it might be another clue. And finally, do you have any job logs you can share (redact anything sensitive please! this forum is public)
Then the other option is to try the Docker Galaxy image. This has all of the basic configuration set up already for you, and has a separate dedicated README for common custom configuration changes. This was just updated.

Let’s start there, thanks!
