Web site requires TLS 1.2. TLS 1.2 is not enabled on WS2012r2 and earlier systems.
[Net.ServicePointManager]::SecurityProtocol

So no way to fix this?

Hi,
You can enable TLS 1.2 if you have it disabled:
/en-us/windows-server/security/tls/tls-registry-settings#tls-12
An easy way to do so, is with the IIS Crypto free tool.
Here's also the supported protocols in TLS/SSL for various of Windows versions:
Protocols in TLS/SSL (Schannel SSP)

No . Just set the protocol.
[Net.ServicePointManager]::SecurityProtocol += 'Tls12'
No need for any fancy tools.
SSL - all versions are no longer supported for any version of Windows. They may exist but disabling most is recommended or required for security reasons. They should/must be disabled in IE.
Almost all web services and sites are now only supporting Tls 1.2.

Also note that some sites may still require SSL 3. W10Pro disables that by default but it can be added in the same way.

Not sure where to add the [Net.servicePointManager]...etc] but I get error: The remote server returned an error: (401) Unauthorized.

You cannot use Windows credentials to non-Windows services. You must contact the site and find out how to authenticate if it is allowed.
The TLS obviously worked.

It uses the SFTP - SSH File Transfer Protocol.
I can log in through Filezilla. Just wanted to automate some processes no port, logon type normal

DownloadFile does not support SFTP. You will need to use a third party solution.

Actually I got it, edit the regisitry to disabled the tls and removed the[Net.ServicePointManager]::SecurityProtocol += 'Tls12'.
Then it worked

You didn't need to do that and SFTP is not the method required. Do NOT disable TLS in the registry. That was no the issue. Somewhere you gave us bad information. Now you will always fail on all sites that require TLS.
Without accurate technical information there is no way to analyze your issue.

Right now I am only messing around in a Test VM. We have scripts that disable the TLS in the registery for what we do.
