Does W2D4_Tutorial4 need ngrok authtoken?

Thank you for reporting this issue. I will contact the content creators and we will push a fix if needed!

@lanluo9 I have contacted content creators, and they notified me that ngrok now accepts only registered users (free registration via a personal authentication token). We have updated the notebook and now everything works following the updated instructions. Thank you for reporting it. Next year we will consider to remove ngrok and use an alternative.

Thanks for fixing the authtoken! I'm going through the updated notebook and noticed that after a few times, launching a new flask app on ngrok will get the user stuck on the ERR_NGROK_6024 page. I've tried using Chrome, Firefox, Edge, and they all get stuck the same way.

Clicking the "visit site" button doesn't do anything. I also see other people getting stuck on this error page: https://stackoverflow.com/questions/72802372/ngrok-warning-bypass-in-iframe

The error page says that it can be avoided by setting and sending an [ngrok-skip-browser-warning] request header with any value. After some searching I couldn't figure out how to do it; could there be a line of code added above to do that?
