Connection to kernel failed

Dear SWAN team,

over the past few weeks I have been having connectivity issues while using SWAN.

When I run a cell, my notebook inevitably loses connection to the notebook server and the following error message is displayed.

“A connection to the notebook server could not be established. The notebook will continue trying to reconnect. Check your network connection or notebook server configuration.”

Once the connection is lost it cannot be reestablished using the “not connected” button on the top right of the window and I have to restart the session.

I am running SWAN on safari, my machine is connected to the CERN network and I use the default environment configuration. I have tried increasing memory / number of cores to no avail.

Do you have any tips as to what I can change in the configuration to have a more stable connection?

Thanks,
Jedd
