504 Gateway Time-out nginx/1.17.8

When I open this topic’s Lecture page, the page takes a couple of minutes of loading and then returns this error message instead of returning a Jupyter notebook:

504 Gateway Time-out
nginx/1.17.8

I am unable to proceed. Has someone else had this problem?

I too have this exact same problem, and I’ve added the cookie it requested to be added as well.

Oh yes, I did this as well but forgot to mention that, thanks for the comment

I am also trying to open Module 1 Tabular Data Exploration Lecture or Jupyter Notebook but it’s giving error.

504 Gateway Time-out

In my case requested cookies are already allowed, still it is not working. It was working well 3hours before

Hello,

The Jupyterhub server encountered an issue this morning. We are very sorry for the inconvenience caused by this technical problem. We are currently investating on what caused it.

But it should be back to normal now.

@Marc_In_Singapore That is a preferable alternative, thanks for sharing!

@brospars Thanks for the speedy response, it is indeed working for me now

Thanks God, its back to normal.

Ok, server back up and working.

Hi, it´s Saturday, 4:35pm and it seems the jupyter server is down. Cannot start any notebook. Always get 504 Gateway Time-out / nginx/1.17.8 error.
Hopefully someone can fix it so we can work over the weekend.
Best regards, Thomas

Hi. I have the same problem, I can not view nether the data nether the jupyter notebooks!

ok, I try to restart it !

It’s ok, the server is working now

The «Tabular data exploration» and «Fitting a scikit-learn model on numerical data» worked, and the the «Handling categorical data» sheet returned a 504 Gateway error

It’s ok for me, could you try again ?

Perfect timing for a short break, Fun-Mooc rocks

Please let us know if you encounter the same problem again. We will inform you about it on the Course information page.
