@khongi - hoping you can answer this question. I've got a similar set up to this, and am having problems with the subcontainers attached to QBT stopping. They stop, then I have to restart them manually. It's easy enough but far from the automated set up I want. I've got the restart set to always for example on my Jackett container.
