Re: Error 524 on jupyterlab

Hi,

I cannot access Jupyterlab by web interface. It still works by ssh. I've followed the support documentations, but nothing works.

My best guess is that the main issue is with the opened ports of docker.

curl http://127.0.0.1:8080/api/kernelspecs
curl: (7) Failed to connect to 127.0.0.1 port 8080: Connection refused

I have the full result of the following command available, but i'm not sure if it's good idea to post it in public.

sudo -i
cd /opt/deeplearning/bin/
./diagnostic_tool.sh

I think the main error is from:

{"log":"2022/11/05 08:47:34 Health Check request failed: Get \"http://localhost:8080/api/kernelspecs\": dial tcp [::1]:8080: connect: connection refused\n","stream":"stderr","time":"2022-11-05T08:47:34.588994439Z"}

Thanks

One possible solution is to perform disk check and repair using this command: sudo fsck /dev/sdb then reboot your machine.

You can also migrate data of /home/jupyter/ folder and upload it to a new instance as a workaround.

Hi,

This solution doesn't work

Please have a look at that thread: https://stackoverflow.com/questions/74326566/jupyter-internal-api-is-not-active-vertex-ai-jupyterlab...

Since documentation and the workaround does not help, you may file a 1:1 Cloud Support here: https://cloud.google.com/support

A support resource that has access to your project will be able to check more thoroughly some components around your Jupyter notebook and can give you more comprehensive answers and suggestions.
