On notebook page i get this error : “A connection to the notebook server could not be established. The notebook will continue trying to reconnect. Check your network connection or notebook server configuration.”

RESOLVED:

I tried reserching some more on this error and found a very helpful advice from Jupyter Notebook Kernel Not Connecting: Connection Failed · Issue #5024 · jupyter/notebook · GitHub which suggested to find the most common error type in the traceback messages on terminal. Upon checking my terminal i found out the following error:

“ImportError: DLL load failed while importing win32api: The specified module could not be found.”

Further googling i found this page relevant to this error

which suggested to install pywin32 using the following command relevant for conda environment as i am using conda enviroment:

conda install pywin32

and when tried to launch the notebook again from terminal, lo and behold it connected instantaneously…Hurray!!!

Worked for me, too! Thanks.
The message said pywin32 was already installed, but seemed to work after I ran the command.
