I am not able to access jupyter lab created on google cloud enter image description here

I created one notebook using Google AI platform. I was able to start it and work but suddenly it stopped and I am not able to start it now. I tried building and restarting the jupyterlab, but of no use. I have checked my disk usages as well, which is only 12%.

I tried the diagnostic tool, which gave the following result: enter image description here

but didn't fix it.

Thanks in advance.

  • Do you mean that the problem persists even after creating a new JupyterLab instance? If you are just restarting the existing instance, how are you doing it? If you are restarting just the kernel, then can you please try stopping and starting the VM instance from the Notebook instance page as suggested [here](https://cloud.google.com/notebooks/docs/troubleshooting?hl=ja#jupyter-api_status_failure)? – Krish Aug 23 '21 at 10:14
  • yes, the problem existed even after restarting the VM instance multiple times. – Deepak Aug 23 '21 at 11:20
  • Can you check the log? you can easily check it by clicking on user-managed notebook tab and then clicking log tab. In my case, I found `ImportError: The Jupyter Server requires tornado >=6.1.0` – masaya Aug 15 '22 at 08:44

The error might be caused by a corrupted disk partition “/dev/sdb”. After connecting to the notebook instance through SSH, run sudo fsck /dev/sdb to perform a disk check and repair, and then perform a reboot.

In case this does not help, you can download your data after zipping the required content from the “/home/jupyter/” folder and upload it to a new notebook instance.

Below is the zip utility command for your reference.

cd /home/

sudo zip -r test-1.zip jupyter/

For me I faced this issue When storage was full after increasing it started working.

You should try this Google Notebook trouble shooting section about 524 errors : https://cloud.google.com/notebooks/docs/troubleshooting?hl=ja#opening_a_notebook_results_in_a_524_a_timeout_occurred_error
