Registry tweak on local machine fixes this

Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework\v4.0.30319]
"SchUseStrongCrypto"=dword:00000001
[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\.NETFramework\v4.0.30319]
"SchUseStrongCrypto"=dword:00000001

Thanks for reporting, development is currently working on a solution. This relates to the deprecated TLS 1.0/1.1 protocols. A workaround for now would be to have your users login to your instance directly using your Control URL.
