I can no longer access Courser JupyterLab: https://labs.cognitiveclass.ai/tools/jupyterlab/lab/tree/labs/DL0321EN/DL0321EN-2-1-Data-Preparation-py-v1.0.ipynb for the course https://www.coursera.org/learn/ai-deep-learning-capstone/home/welcome.
The error I receive is
"502 Bad Gateway
The server returned an invalid or incomplete response."

It was working fine till 2/25/2020

unable to "share on github" from jupyter, github returns a "404 not found page" so you're using an old OAUTH link - please fix this, this was working before

Unable to open Skills Network Labs. I get the following error message. I've tried logging off and reloading the site several times but with no luck. I get the following error message: 500 Internal Server Error Cici Mud Sorry, something went wrong. Please try again. If this does not work please open a support ticket.

Hi there,

After clicking JupyterLab link.
Starting Docker Container message is displayed. And then Blank screen is displayed. PSA

Please guide to start JupyterLab and start using Jupyter Notebooks.

Thanks in advance.

I am not able to see any lab exercises in the lab. Instead there is an ERROR.md file existing in my lab. The error message shows "If you're seeing this file, it's because we weren't able to find your real files. Please contact support using the tab on the side of the screen."

IF

1. This service is being paid for


2. Your Jupyter Notebooks service is often down


3. The course is paid for on a monthly basis (Time = Money)

THEN

You should provide the .ipynb files for student to store on their own device to complete lab sessions

ELSE

Respond to user queries/ Get it fixed quick

AND

Refund everyone for the time the service is down/intermittent.

OR

Provide the service at no cost.

Hi,
Since yesterday after running a few commands I am getting 502 bad gateway error again & again and not able to connect to the jupyterLab now. Stuck with my project, please suggest....!!

I'm unable to open Jupyter notebook. I keep getting this page and it never opens.

I would like to open a discussion about the working materials in the Jupyter Notebook labs. About the quality, the positive or negative remarks. Also, about some parts that are a bit unexplained or can be done differently. In other words, my idea is to post some feedbacks about the Jupyter Notebook labs.

i receive many errors when i try to execute the SQL query

I'm unable to start lab from edx and getting the error page.
Attached is the page for reference.

Everything was working fine until yesterday(9 June 2020), Suddenly on 10 June, I lost access to jupyter notebooks on Skills Network Lab with "500 Internal Server Error". Fix this ASPA I'm losing my time.

When I tried to enter the practice lab, it said '422 unprocessabel entity'.

How to fix it?

I am not able to find files (Jupyter Notebooks) under lab section on Jupyter Lab.

It says:
Cannot openCould not find path: /labs/DV0101EN/DV0101EN-1-1-1-Introduction-to-Matplotlib-and-Line-Plots-py-v2.0.ipynb

Also all the previous files are missing from labs directory.
How can I practice, if I do not get the jupyter files with exercises in it. There were other directories too, from other courses.
Please restore everything for me.

All my course material is vanished, I am not able to access the coursera course material and my jupyter notebook is also not opening up.

Despite Torchvision librairy is correctly installed (conda list show the package as 0.2.1 version), the import (ie "import torchvision.transforms as transforms") cause an error ("cannot import name 'PILLOW_VERSION'"). Tried to install a newer version of Torchvision (0.4.2) but cause another error.
