I am using Python 2.7 on Windows 10 (64) computer. Whenever I work with Jupyter notebook, it dies for no reason. Sometimes it dies while I am using it, sometimes when it is idle. I receive below error messages.
Error message screenshot
When I check the command line, the error says:
Assertion failed: Connection reset by peer (bundled\zeromq\src\signaler.cpp:181)
I'd appreciate any help on how to fix this problem. Thanks

Being a student and working every day with VSCode and .ipynb files, I was very surprised to see that, from one day to the next, the following error appeared when I tried to run a cell on one of my notebooks.
Failed to start the Kernel.
Jupyter server crashed. Unable to connect.
Error code from Jupyter: 1
After having tried the different solutions proposed by other topics, uninstall and reinstall, check that no server was working on the same address, nothing happens, the error persists.
My pc recently started giving error in installing Django.... Look at the error message, what could be the cause please?
I tried installing Django for my project, and it just throw an unexpected error message.
I have the right Venv activation code so I expected it to work.
This could be due to a weak internet connection, i.e it takes time to download, or slow internet connection. Check your internet speed and try again. If it still persists, on your virtual env try to install it manually, you can use this video as a guide here.
I am fairly new to working with python, so I am sorry if this is a naive question.
I have set up a jupyter notebook that I start through the windows terminal. I run it with python 3.9.7 in an Anaconda virtual environment. I use microsoft edge as host browser because I had problems with google chrome blocking jupyter lab.
Since yesterday, I receive an error message after opening my notebook with - jupyter lab command (which has worked for me since some weeks now). The puzzling thing is, that I can open my notebook and work in it for some minutes usually, but then this message pops up:
Server Connection Error: A connection to the Jupyter server could not be established. JupyterLab will continue trying to reconnect. Check
your network connection or Jupyter server configuration.
Unfortunately, I have really no idea why this could be, therefore I have not tried much to fix this yet. I have a stable internet connection. Simply closing the notebook and reopening it worked for some times, but after a while of working in the notebook it looses the connection again.
Has anyone experienced similar problems?
Thank you for your help and ideas!
I had this issue with jupyter lab my error seems the same:
"A connection to the Jupyter server could not be established.
JupyterLab will continue trying to reconnect. Check your network
connection or Jupyter server configuration."
The problem for me was that I had started the program from the command line using the "jupyter-lab" command and had subsequently closed my terminal after the jupyter lab opened. Closing terminal shut down the required server. Left the terminal open and is working normally.
I am trying to run cells inside Jupyter Notebook, but it keeps on giving me this strange error. I am not sure if it is related to VS Code update or something else:
Failed to connect to remote Jupyter notebook. Check that the Jupyter Server URI setting has a valid running server specified. http://localhost:8888/ TypeError: request to http://localhost:8888/api/contents/?1589373068313 failed, reason: connect ECONNREFUSED 127.0.0.1:8888
Has anyone encountered this issue?
Thanks!
