pip install times out: 'Failed to establish a new connection [Errno 110001]'

Python version

pip version

23.2.1

Problem description

I've installed a fresh version of Anaconda (v23.7.4) and attempted to install some packages using pip and a standard requirements.txt file (numpy first).

Basically, when I run anything to do with pip install, the request times out and does the 5 retries. My suspicion is an SSL certification problem but I'm not sure.

I note that conda installations do work (e.g conda install ...) but there are certain use cases and packages which only pip supply.

Running the following command in Anaconda prompt (within a conda environment):

pip install --upgrade -vvv -r requirements.txt

Gives:

I am able to ping the website https://pypi.org/simple in Powershell and access through the browser:

ping www.pypi.org

And when I run pip config debug I get:

env_var:

  C:\ProgramData\pip\pip.ini, exists: True
    index.url: https://pypi.org/simple

Finally, I attempted to access the packages programmatically using requests:

import requests
response = requests.get("https://pypi.org/simple/")

which yields:

Any help would be greatly appreciated - apologies if this is blindingly obvious.

Hi, I've met the same problem. Can I know how you solved it?

[jeanas]

Maybe the Windows antivirus is blocking the connection?

Hi, I've met the same problem. Can I know how you solved it?

I was installing a conda environment in Windows wsl. Network connection was fine but pip install <package> failed with NewConnectionError Failed to establish a new connection: [Errno -2]. Solved by restarting wsl: wsl --shutdown

@f-zl Thanks, this resolved the issue for me as well - Windows 11, using WSL1 Ubuntu 22.04 installing Python 3.12 in conda. Pinging websites was fine, my other conda environment with Python 3.11 was also fine. Restarting WSL with wsl --shutdown immediately fixed it for my Python 3.12 environment
