Ssl Certificate Issue in Tortoise Git

I had a very similar problem. I work under a corporate firewall.

OS: Windows 10

Problem: When attempting to use "git clone" I receive an error fatal: unable to access ' SSL certificate problem: unable to get local issuer certificate

Re iterating general instructions in case the linked post goes down and some minor differences I encountered.

1. Navigate to the site you are trying to get things downloaded from.
2. Following the steps in the Microsft article: Click the padlock in the browser and download the root cert. This is where I had to do something slightly different. I had chained certs, so I downloaded all of them except the deepest cert.
3. Continue to follow the steps in the above article, switching to using a private copy of the git root cert store. My path differs for git than most because I am using git for windows 2.5.x, located under c:\program files\Git\mingw64\ssl\certs\ca-bundle.certs
4. Then point git to use your local file as in the article git config --global http.sslCAInfo C:/Users/yourname/curl-ca-bundle.crt
5. copy the downloaded certs into the bundle and restart your terminals or computer.

Something that hung me up for a bit was differnce between admin user and local user, setting a global config in windows will create a user based local copy and not update your cert location correctly when using git config

Super helpful for me diagnosing where my config was looking for search: git config --list --show-origin
