I use windows 7 x64.
I have a clean install of Julia v1.4 but still have the problem.

The possible enumeration values are “Ssl3, Tls

It maybe that you have to enable TLS 1.1 and 1.2 on your client:

But it would be much better to upgrade to Windows 10. Its still for free!

And to be sure (if you stay with Windows 7) you should upgrade your PowerShell to some
recent version:

Thanks.
Installing the latest PowerShell will solve the problem.

Which one? PowerShell? TLS 1.2? Or both? Just curious for others.

I installed the latest Power Shell
