Google Colaboratory and Google Drive integration fails

Question

I am not able to save a new notebook in my Google Drive environment.

Google Colaboratory works with predefined notebooks such as Hello, Colaboratory, but I am not able to save any into my Drive folder. I have the Colaboratory app allowed in the Google Drive settings and really dont know how to solve it. Colaboratory communicates with Drive - it even creates the notebook files in the Google Drives folder, but when loading any notebook file it always report following Notebook loading error

There was an error loading this notebook. Ensure that the file is accessible and try again.

Neither the details of the error help much:

Failed to fetch TypeError: Failed to fetch

I was playing with the access rights of both the file and the folder and could not find any solution.

Update: Chrome 64.0.3282.167 (64 bit); Windows 10 1709. I use two users on the Chrome. Creating Notebooks works normally on different computers with my username. This is the output from console: Chrome Console Output

What browser, browser version, and OS are you using? Do you see any errors in the JS console? Are you using multilogin (multiple users logged into the same profile)? — Craig Citro

I guess, you need to do the authentication each time you load your file. — Rika

On Google Chrome, I was seeing this issue randomly and it mentioned not being able to load the file /some/google/path/thats/gone/because/this/fixed/it/client.js. I tried clearing my cache and hard reloading, and sure enough, Colab starting working again.
