I am trying out Google Colab, but then I keep getting this pop up box that says:
Error Could not access the resources needed to display output. This is prob
The output cell is an element. It has a url like
https://jbe1910iol-colab.googleusercontent.com/v2/usercontent/8b5e8f2bbe60490e/outputframe.html
So, you can try adding [*.]googleusercontent.com to the whitelist as well.
[*.]googleusercontent.com
Not sure if it will work though. Hope it does.
