Trouble connecting VS 2010, 2012, and 2013 to azure devops server 2019

I am facing an error when I try to connect Visual Studio 2010, 2012 and 2013 to our Azure DevOps Server 2019 instance. In each of those versions when I attempt to add the server I get an error

TF31002: Unable to connect to this Team Foundation Server.

Technical Information: The request was aborted: Could not create SSL/TLS secure channel.

If I try to connect again after that I see this message.

The underlying connection was closed: An unexpected error occurred on a send.

I am able to connect without error on VS 2015, 2017 and 2019. I am having this problem on multiple machines. The machines are on Win 10 and Win 2012R2. Also from these machines I can hit the TFS https web sites, team projects just fine.

I found the fix. Looks like it is a TLS issue.

Run this from powershell:

reg add HKLM\SOFTWARE\Microsoft.NETFramework\v4.0.30319 /v SchUseStrongCrypto /t REG_DWORD /d 1 /f /reg:32
