HTTP error while using conda for installation of any packages

Question

CondaHTTPError: HTTP 000 CONNECTION FAILED for url onda-forge/linux-64/repodata.json> 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.

SSLError(MaxRetryError('HTTPSConnectionPool(host=\'conda.anaconda.org\', port=44 3): Max retries exceeded with url: /conda-forge/linux-64/repodata.json (Caused b y SSLError(SSLError("bad handshake: Error([(\'SSL routines\', \'SSL23_GET_SERVER

Can you tell me what should I do next? I surfed other links and setting ssl_verify: False didn't work for me

I'm voting to close this question as off-topic because your question is more appropriate for the StackExchange sites Super User or Unix & Linux. — David C. Rankin

I am experiencing the same issue, and am quite confident it is due to SSL/Firewall issues internally in the workplace.

Do you have proxy servers that you need to specify in your .condarc file? (.e.g)

proxy_servers:
    http : http://101.101.101.255:8080
    https : https://101.101.101.255:8080

I know it says WinXP but this still applies - https://conda.io/docs/user-guide/configuration/use-winxp-with-proxy.html

If you are specifying your organisation's servers correctly, and are still having these issues, then there is likely a firewall exception / SSL cert configuration issue that needs to be resolved, and is not a conda issue per se, but a networking problem
