Create new Python environment

[shafitrumboo]

I'm trying to create new environment using ArcPro 2.4 and also trying using command prompt but it shows error and that is.

CondaError: CondaHTTPError: HTTP 000 CONNECTION FAILED for url <https://conda.anaconda.org/esri/win-64/mkl-2019.3-arcgispro_203.tar.bz2>

An HTTP error occurred when trying to retrieve this URL.
HTTP errors are often intermittent, and a simple retry will get you on your way.

I'm suing ArcGIS Pro 2.4 and windows 10

I've also noticed in the past:

From one source aws server ip:

https://services.arcgisonline.com/ArcGIS/rest/services/World_Topo_Map/MapServer
is accessible using manual proxy server only.

yet,
https://internaldomain.example.com:port/webUrl
only available using the .pac setup script

In order for the .example.com addresses to work, I had to add *.example.com to the list of exceptions for the manual proxy server.

This is weird because in another equivalent server ( which has the same proxy/lan configurations----except the *.example.com exception) can reach both sites using the .pac setup script.
Other aws servers even only require the .pac setup script only!

I reference something similar here:

In our case, the problem was a network firewall. I resolved it by going off-network and using WiFi.

First, I had my company cyber team whitelist the recommended Esri and Conda urls to be allowed on the proxy:
http://downloads.esri.com/resources/enterprisegis/AGOL_Domain_Requirements.pdf 
https://community.esri.com/thread/211474-web-appbuilder-login-issue-using-internet-explorer-11 

https://*anaconda.org 
https://*.anaconda.com 

https://*.conda.io 

Then, I resolved by adding the http_proxy and https_proxy system environment variables:
https://conda.io/projects/conda/en/latest/user-guide/configuration/use-condarc.html#configure-conda-...
Configure conda for use behind a proxy server (proxy_servers)
By default, proxy settings are pulled from the HTTP_PROXY and HTTPS_PROXY environment variables or the system.

set them to http: http://proxy_server:port and https: https://proxy_server:port, respectively

After installing the Esri package, I removed those environment variables, since they were conflicting with access to other urls.

Alternatively, within anaconda itself, set these configurations:
conda config --set proxy_servers.http http://proxy_server:port
conda config --set proxy_servers.https https://proxy_server:port

For anyone experiencing this problem, for me it has to do with a similar problem with pip where your enterprise SSL connection is not trusted by the package manager endpoints... the solution for me was to use the -k flag for insecure connection:

conda create -k --clone arcgispro-py3 --name arcgispro-py3-clone

Thanks for your help Kory and Andres.  I'm slowly working my way through this problem between my work computer and my home computer.  It's definitely my work computer that has the issues.  For one, we use Zscaler and the first package (.bz2) is being blocked as unscannable.  I think we will have to add exceptions for those.  Also, we're having SSL errors, probably because of our root certificates.
