SourceTree unable to access remote Git? error:1407742E:SSL

Unreal Courses Ask

While I am following this course, I am also involving myself with an existing Unreal project with friends. So I am trying to apply what I learn here, to the existing project.

I used Github, Git LFS and GitDesktop as client for the project which worked fine.
Now I am trying to set up SourceTree to replace GitDesktop because it just looks a lot cleaner. However, when I try to Pull or Fetch the remote Master to my local version, I get the following error:

git -c diff.mnemonicprefix=false -c core.quotepath=false fetch origin
fatal: unable to access ‘https://github.com/MattSowards/BattleForItAll.git/’: error:1407742E:SSL routines:SSL23_GET_SERVER_HELLO:tlsv1 alert protocol version
Completed with errors, see above.

I did make sure I fully updated SourceTree and Git to the latest versions.
I also read that Git deprecate weak cryptographic standards. But I have set SourceTree to use System Git instead of Embedded Git

Is there something I’m missing?

Are you on a Mac? If so I had fun and games fixing it myself. It was hard to get MacOS to update it’s TLS version

Let me know we’ll see if we can help further. @DanM and @sampattuzzi any further ideas?

Sorry for forgetting to mention my OS. I am so used to Windows that I kinda forgot that this course also covers Mac users.
I run Windows 7 Ultimate.

The cause (on the GitHub end) is here: https://githubengineering.com/crypto-removal-notice/

Possibly useful information here: https://community.atlassian.com/t5/Sourcetree-questions/Sourcetree-support-for-TLS-1-2/qaq-p/735270

Also, your system git shows 1.9.2, current version is 2.16.2

Okay, so as I mentioned in my OP, I knew about Git disabling some kind of protocol that stopped older versions from functioning with SourceTree. But I was convinced I completely updated my Git since it didn’t give me an option to update it anymore.
Guess I was wrong…
After manually downloadng Git 2.16.2, it now works again.

Thanks guys!
