That is what happens when you try to connect version 3 of the server
with version 4 of the SDK: OAuth authentication fails with this
unexpected error. Are you sure you are using version 4 of the engine?
Can you try a simpler request? For example, try this example:


https://github.com/oVirt/ovirt-engine-sdk/blob/master/sdk/examples/test_connection.py

That will generate an "example.log" file. Can you share it? Take into
account that the log will contain your password, so make sure to remove
it or share it privately.
