I was working on the Notebook instance yesterday and was able to run some scripts successfully, but this morning I was unable to connect to the notebook instance. I keep on getting the loading icon before 504 error appears. Not sure if this is related to memory since I am currently using t2.medium and I can upgrade if that's the case. My only concern with this is that the data shouldn't be lost.
Any help on how I can check what issue is will be appreciated.
