Connection lost after (about) one minute

Hi, when using Jupyter-collaboration on Jupyverse, it seems that staying disconnected for more than about 60 seconds while computing causes the connection to the server to be lost. I’ve done some tests to confirm this. If the page is kept open, everything works fine. If you disconnect for 30 seconds, it works fine. If you stay disconnected for some minutes but the computation lasts for less than 60 seconds, it still works fine. But beyond about 60 seconds of computation in which you are disconnected, the connection that returns the output is lost. Is it possible that there’s an intrinsic timeout somewhere? I’m attaching a screenshot of what happens. I lunched the code, disconnected after few seconds and then reconnected after some minutes, in the first case the output is truncated, while in the second the output is fine.

Here my configuration (and thanks again for the help in setting this up).
