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.
Solved! Go to Solution.
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.
@BenJackson are you able to share any of what you learned from Esri, and/or how you resolved this issue? I'm facing the same issue in https://community.esri.com/t5/arcgis-notebooks-questions/notebook-disconnected-error-following-succe...
It's been a while since I looked at this so I can't really remember the fine details, but I dug through my emails and it appeared to be related to domains requiring whitelisting on their firewall as listed by this document: http://downloads.esri.com/resources/enterprisegis/AGOL_Domain_Requirements.pdf
When I tried to load the page I linked to, it suggested it was down for maintainance, if that is not the case and it no longer exists, maybe someone from ESRI can help you locate the new version of the document or you can access the page using the internet archive.
Thanks Ben. I now see that didn't read your posting clearly enough. We're not ArcGIS Online users, but rather run ArcGIS Enterprise locally in our own environment. We encounter the same error as you described, but I now see that what you learned is not very applicable to our situation.
But thanks for taking the time to respond to my query.
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.
