Port 465 - smtps. it is not supported by .net
https://docs.microsoft.com/en-us/dotnet/api/system...
here they write that StartTLS is used, which means you need to use a different port - 587
and starttls: You
$SMTPClient.EnableSsl = $true
may need more

[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12

and here is a big discussion with examples of what else you need to enable in your Google account (access to less secure app)
