I am unable to use JupyterLab for more than a few hours. The log files indicate an issue with a TCP connection used by Jupyter. (for the details see below)

I was told that some application must be killing this TCP connection. However, I have no idea how to troubleshoot that. Could you help me to find out the root cause or any practical solution?

Are there tools to find out why is this connection lost? Are there alternative connection methods for Jupyter? Are there ways to protect a connection?
