I tried to use the Jupyter Notebook application as usual but, I could not connect to the Kernel ( python(base) ) when I launched the the jupyter notebook from my CMD line,the notebook launched fine but it was impossible to execute any code since it couldn’t connect to the kernel.
But when I launch the jupyter notebook from the anaconda navigator, it works well and connects to the kernel.
I have looked at documentation and all the threads that I could find but nothing solved my solution of connecting with the kernel. I tried downgrading tornado, re-installing everything but it did not work. I would be very grateful if someone could tell me what i am doing wrong.
The below screenshot shows, the jupyter notebook launched from anaconda navigator and the kernel was connected:

The below screenshots show the jupyter notebook was launched from the cmd, and the connection to the kernel was not established:


Please help me to find a solution.
Thanking you in anticipation!
