Notebook on ArcGIS online unexpectedly disconnected

[BenJackson]

One of my users is having a problem with opening a notebook that I am hosting on ArcGIS online. They always seem to receive a message: "Notebook disconnected: Your active notebook session has unexpectedly lost connectivity....". They have tried multiple browsers and have tried in private tab mode. I personally have no problems accessing the notebook, so I am not sure as what else to suggest.

I would reach out to Esri Technical Support on this. They may be able to investigate in more detail.

OK thanks, I've opened a ticket, hopefully they can provide a solution.

I ran into the same issue and it happens a lot. I'm not surprised if I see this message from Notebook server deployed with ArcGIS Enterprise, but it's very annoying that this message pops up from ArcGIS Online.
