.NET8 MAUI trouble with SSL authentication (only happens on Android)

[philipkfchan]

When calling SslStream.AuthenticateAsClient(..) while passing in *.companyname.com as targetHost, I get the following exception. I'm able to bypass this exception if I modify the targetHost slightly to companyname.com, but this won't be appropriate when we move to production. Does anybody know why the substring *. is considered to be invalid input, as stated in the exception? Again this only happens when I debug launch in Android and not Windows:
