Authentication failing with 421 status code

[h-azycrazy]

When trying to authenticate with taking client-id reference from pyicloud, and passing in correct credentials, getting 421 error code from authentication.

This is happening while running the TestDriveService test.

Actual response from the test case:

Failed to log into iCloud: 1.0 java.lang.RuntimeException: Failed to log into iCloud: 1.0 at com.github.tmyroadctfig.icloud4j.ICloudService.authenticate(ICloudService.java:212) at com.github.tmyroadctfig.icloud4j.ICloudService.authenticate(ICloudService.java:186) at com.github.tmyroadctfig.icloud4j.ICloudTestUtils.getServiceFromSystemProperties(ICloudTestUtils.java:41) at com.github.tmyroadctfig.icloud4j.TestDriveService.testListItems(TestDriveService.java:45)

Here's the response object - in debug mode:
