Jupitor is not working

jupitor console is not responding to the tasks or instructions

Hi, Anirudh.

Can you send the screenshots of the error? or the page that says that it is not working.
I have rechecked your account. Your jupyter is working perfectly.

All the best!

Yes it was working after that. Please give me an example of ```
find . -name ‘*.txt’

It is not working for myfirstfile.txt. 
where am I getting it all wrong?![Screenshot%20(37)|690x387](upload://5ygQ3KYIFmvC3g5Ye3yruPOpTjA.png)
