Additional Information

@Denestel thanks for the report!

The version of Git embedded in Desktop uses the Windows SChannel APIs for validating certificates as part of the HTTPS handshake. We've had various reports of this failing due to other tools being installed alongside, like anti-virus programs, or being behind some proxy servers.

As a workaround, you can revert to the classic OpenSSL behaviour by opening the repository in a shell and running these two commands.

$ git config --global http.sslBackend "openssl"
$ git config --global http.sslCAInfo [path to .pem file]

The PEM file is just a bundle of public certificates to validate - the PEM file distributed by the cURL team should do the trick.

We're working on explaining this error better in #3406. Please follow along with that issue.

Check your "/.gitconfig" for proxy configuration, or anything else that might be providing wrong credentials - Had the same issue, and it turned out to be the corporate proxy settings.

I have also figured out (Based upon AndyGee's suggestion regarding .gitconfig) that if you are in a real bind you can add to the following section. (This may present security concern but could help in a pinch)

[http]
sslVerify = false

Then restart the app
