Connection failed

[balintbiro]

Hey All,

I am trying to run C++ from Jupyter Notebook. Installed Xeus and Cling following this step-by-step guide (https://www.pranav.ai/cplusplus-for-jupyter). When I open a Notebook, I can set the Notebook type to C++ (11,14 and 17) however it can not connect to a server and gives this error message:
"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.".
I was trying to search for that particular message but did not find anything.
Did any of you face the same problem before? Any suggestions would be highly appreciated.

Thanks
