Conda ProxyError

I am trying to install conda packages/create environments behind a corporate firewall

On another machine, I managed to install packages from conda default channels by setting the HTTP/HTTPS proxies and ssl_verify: False in conda config.

However, I am now getting ProxyError: Conda cannot proceed due to an error in your proxy configuration. Check for typos and other configuration errors in any '.netrc' file in your home directory, any environment variables ending in '_PROXY', and any other system-wide proxy configuration settings.

I have verified that conda is not accessing any .netrc file through conda info

.condarc:

channels:
- defaults

# Show channel URLs when displaying what is going to be downloaded and
# in 'conda list'. The default is False.
show_channel_urls: True
allow_other_channels: True

proxy_servers:
    http: http://abc.cde.local:XXXX
    https: https://abc.cde.local:XXXX


ssl_verify: False

Here are the steps I have tried to resolve my issue:

  1. I have verified that the proxy URLs are correct and can make outgoing requests through these URLs
  2. I have tried to set the two settings both through conda config --set and .condarc
  3. I have tried to set the proxies through environmental variables

I cannot make changes to Windows proxy settings or do anything that requires any admin permissions.

Does anyone have any experience with this?

If you know your condarc file is correct, on Windows you need to make sure that your environment variables are "http_proxy" and https_proxy", lowercase.

Also, most proxies use an unencrypted traffic to the proxy. So make sure the URLs to your proxy are both http://

Finally, when you change your enviroment variables in Windows you must start a new powershell session for the changes to take affect.

This and the correct conda RC file solved it for me.
