Can not install SourceTree. Error "maybe the site uses obsolete TLS"

[Garmash Maks]

Win 10, insider previev, build 17134.48. I can not install the SourceTree program https://www.sourcetreeapp.com/

You receive an error message: "

I can not safely connect to this page
It is possible that the site uses outdated or unreliable security parameters of the TLS protocol. If this repeats, contact the website owner.
Try the following:

Back to last page
Change settings
"

I ask you to suggest what to do?

The answer is in the problem report - you should get the owner of the website to replace the TLS protocol with one that has not been compromised (some versions of TLS were broken a while back, which is why applications are refusing to use them)
