Description
Hi,
I am having a problem with launching Jupyter Notebook, it produces the following error:

_TimeoutError: [WinError 10060] A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond_
All I did by yesterday is installing VirtualBox, uninstalling Microsoft Visual Studio, but, it has still worked for me by yesterday!
This morning, I try to open my notebook and it shows that error, I had:
- Un-instaled and reinstalled Anaconda!
- Deactivated completely my Firewall and my AV.
- Added exception for my firewall to allow full in-out connections through port 8888, and allow full permission to python/anaconda
But still, without success!
Does anybody get a clue about this?
Thanks, I appreciate

Research direction
The report names no repository files or tests; begin by reproducing Jupyter Notebook launch on Windows and examining the reported TimeoutError [WinError 10060]. The issue records firewall, antivirus, port 8888, and Anaconda reinstall attempts, so done would be identifying the specific cause of the connection timeout and confirming that Notebook launches successfully.
