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

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.

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

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.

Coursera course assignments to Skills Network Labs are not opening. It says path not found - Could not find path: /labs/DV0101EN/DV0101EN-2-3-1-Pie-Charts-Box-Plots-Scatter-Plots-and-Bubble-Plots-py-v2.0.ipynb

I'm getting this error for almost a month now. Donno why IBM and Coursera sponsor such courses.
Screenshot of error is also attached. Pls resolve this issue at the earliest.

This is a example link, all the Lab in coursera cannot open, and all my old record and saves are gone..

Hi, I can not access labs for Deep Neural Networks with PyTorch, It is showing "500 Internal Server Error". :(

I am unable to complete my course because jupyter notebooks lab is not working from the past few days and I am getting error 502 bad gate way. Please solve this issue as soon as possible.
'' https://labs.cognitiveclass.ai/login/lti '' this url is not even processing & showing error.

How to fix it?
