Can't clone python environment SSL error

[MK13]

I am utilising ArcGIS pro 3.3.2 and I am unable to clone the default python environment. With previous versions of Pro, I tended to pip install into the default arcgispro-py3 location but that doesn't seem to work anymore so I attempted to clone the default environment. However, that errors out with the SSL error below.

Things that I have tried:

- Run as administrator

- set the security certificate using conda

- allow full control by users on the ArcGIS folder

Hi!

This looks to be caused by a Self Signed SSL certificate. I have encountered something similar and I believe I cleared the ssl certificate cache and then I was able to proceed.

There are some solutions where you set verify to false to skip the check however I can't recommend this due to security issues. I hope this helps!

How do you clear the ssl certificate cache?

We ran into the exact same issue a while back. Same error message, same 0% downloaded messages.  Turns out we were being blacklisted by Anaconda because they thought were a commercial entity.  Had to contact Anaconda, provide our server IP's and a letter stating our organization was not a commercial entity. They were really good to work with and had it fixed within a few days.

I'm running into this issue as well (work in state government). Clearing the ssl cache didn't help. Turns out Anaconda.org is blocked by our IT/security team... So if anyone else comes across this, try accessing their website first to check if that is the case lol. 

Update 5/12/25: This didn't solve my issue entirely but was probably one of multiple roadblocks.
