Answer 1

The DLLs delivered by Anaconda3 are located here: D:\Anaconda3\Library\bin

My workaround: I have copied the following files

libcrypto-1_1-x64.* libssl-1_1-x64.* from D:\Anaconda3\Library\bin to D:\Anaconda3\DLLs.

And it works as a charm!

My original answer got flagged as duplicate because I answered a similar question with the same answer, I wasn't aware that this is not allowed. I have marked my other response as a duplicate. Hopefully, this stays up!

I almost spent two days running in circles trying all the solutions I could find on the Internet, but here is what worked for me.

So, CondaHTTPError aka SSL module is not available error is caused by the missing/misplacement of libcrypto file in anaconda3/DLLs folder:

Tl;dr:

From anaconda3\Library\bin copy below files and paste them in anaconda3/DLLs:

-   libcrypto-1_1-x64.dll
-   libssl-1_1-x64.dll 

Detailed answer:

1. Uninstall any Python versions you have (e.g. Python 3.7 or Python 3.8)

   go to Control Panel--> Program and Features--> Select Python-->

uninstall

2. Uninstall any Anaconda versions you might have (e.g. Anaconda or miniConda) For Anaconda:

   go to Control Panel--> Program and Features--> Select Anaconda-->uninstall

   For miniConda

   go to Control Panel--> Program and Features--> Select miniconda--> uninstall

3. Delete any leftover Environment variables

   go to Control Panel--> System--> Advanced System settings (on left side)--> in System Properties click on Environment Variables button--> in User Variable select Path and click the Edit button--> delete any path related to Anaconda, miniConda or Python.

   E.g.
   C:\Users\Bob \AppData\Local\Programs\Anaconda\...
   C:\Users\Bob \AppData\Local\Programs\miniconda\...
   

   b. If you don’t see any paths related to Anaconda, miniConda or Python; you are good to go.

4. Reboot your machine

5. Download the latest version of Anaconda

6. Run the Installer; keep all the default settings

7. Go to your anaconda3/library/bin folder:

   E.g.C:\Users\Bob\AppData\Local\Continuum\anaconda3\Library\bin

8. Copy these files:

   libcrypto-1_1-x64.dll

   libssl-1_1-x64.dll

9. paste these in anaconda3/DLLs folder:

10. Reopen the Anaconda Prompt and test with any command that requires an Internet connection. E.g. conda update conda Or with conda update --all

Install the latest OpenSSl from this site: https://slproweb.com/products/Win32OpenSSL.html the current latest version is 1.1.1. Now I can install packages via pip and conda successfully.

Answer 6

I had the same error, and I tried most of the methods, but none of them worked. I checked the version of anaconda3 it was 4.2.0 which I realized was in beta which might be the reason.

I solved it by uninstalling everything and installing the latest version (5.1.0). It worked after that.
