ProxyAuthentication fails while updating conda - proxy

Question

I keep getting an error while updating conda:
CondaHTTPError: HTTP 000 CONNECTION FAILED for url https://repo.anaconda.com/pkgs/r/noarch/repodata.json.bz2
Elapsed: -
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.
If your current network has https://www.anaconda.com blocked, please file
a support request with your network engineering team.
ProxyError(MaxRetryError("HTTPSConnectionPool(host='repo.anaconda.com', port=443):
Max retries exceeded with url:
/pkgs/r/noarch/repodata.json.bz2 (
Caused by ProxyError(
'Cannot connect to proxy.',
OSError('Tunnel connection failed: 407 Proxy Authentication Required',)))",
),
)
A reportable application error has occurred. Conda has prepared the above report.
Upload did not complete.
I tried this in the .condarc file
proxy_servers:
http: http://proxy.corp.local:8080
https: https://proxy.corp.local:8080
and
proxy_servers:
http: http://user:pass#corp.com:8080
https: https://user:pass#corp.com:8080
ssl_verify: True
ssl_verify: False

Answer 1

I also got the same error message and it is solved after googling so much.
Steps for solving the problem is given below
Create a .condrac file using the conda config command in command prompt or use a text editor to create a text file. I used conda config for creating the .condrac file
You can add following line into the .condrac file located in your user home directory or home
directory
proxy_servers:
http: http://username:password#proxyIP/Proxy URL:port no
https: http://username:password#proxyIP/ProxyURL:port no
ssl_verify: True
Same file can be copied into your anaconda home directory.(C:\ProgramData\Anaconda3 in my case)
Then run > conda update conda command from your prompt
Then you will be getting the result like below. C:\Users\USER.DESKTOP-BQVL8L4>conda update conda
Solving environment: done
Rerun your installation command. This solution worked well for me. Please try and let me know.

Answer 2

Copy files libcrypto-1_1-x64.dll and libssl-1_1-x64.dll
from the directory ./Anaconda3/Library/bin/
to ./Anaconda3/DLLs.
This method solved the problem that I had
