I have a long-lived WebSocket connection for a live trading application with python. I got the following error in spyder after 4 days of working.
An error ocurred while starting the kernel
No error (bundled\zeromq\src\ip.cpp:629)
I use a Microsoft Windows 365 cloud PC. Windows 10 has been installed on this PC cloud. Does anyone know what is the problem? What should I do to prevent such kinds of errors?

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.
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 new to Anaconda and wanted to get started with Pandas, But unfortunately, when I want to launch the jupyter [notebook], I get the error shown in the Picture
HTTP ERROR: 500
Internal Server Error
RequestURI=http://localhost:8888/tree
I realized that the machine was running on a VPN and for some reasons, ipython could not launch on the Virtual Address.I disabled the VPN and notebook loaded on the browser
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.

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
Today when I attempted to launch the appengine SDK (python) I saw the error "Errors occurred" - see image below. More details:
The log file referenced in the error message does not exist at that location
I tried uninstalling the SDK entirely, and re-installing 1.9.13.msi (python)
It's on Windows 7, 74 Pro, python 2.7
I tried renaming the app files at %APPDATA%/local/temp/appengine.*
I'd been using app engine fine for weeks on this machine. Yesterday my machine failed to go to sleep properly, as it often does. At power up it booted into a new/clean Windows - ie. it crashed and lost all its state. (Warning dont buy a Thinkpad T440s for Windows until they have this fixed..). I suspect that something was corrupted when the machine crashed.
I tried restarting Windows, of course ;)
Any ideas on how to fix this?
Found the answer here: https://groups.google.com/forum/#!msg/google-appengine/Uphb04hV2tg/K6vL4osY_xgJ
I renamed the file 'google_appengine_launcher.ini' at users/[my profile]/Goolge
