Connection failed Kernel

Hi, I am getting the “Connection failed (A connection to the notebook server could not be established. The notebook will continue trying to reconnect. Check your network connection or notebook server configuration.)” error when I try to “Work in Browser” for assignments in Jupyter notebook. Because of this error, I am not possible to run the Jupyter notebook and submit anything. Thank you for your help.

I just tried loading the “Python Basics with Numpy” notebook (C1 W2), and I did not have any issues.

There’s not much we can do about issues between your browser and Coursera’s server.

As Tom says, this sounds like an “IT” problem on your side, so it’s a bit hard for us to really figure out what is wrong. But the first question to ask is: did this used to work and now it suddenly doesn’t? Or is it the case that you’re just starting in the courses here and it’s never worked.

Had the same issue and, indeed, it was related to my laptop. I have a company-managed software (firewall-like) installed that prevented me from running the notebook. Once turned off, the notebook worked regularly.
