Blink Security Camera Binding - Communication error

I have installed the Blink Security Camera Binding. When I try to enable the Blink thing (after configuring it correctly) I receive the following exception:

java.util.concurrent.ExecutionException: org.eclipse.jetty.client.HttpResponseException: HTTP protocol violation: Authentication challenge without WWW-Authenticate header

The Github page states the following:
The URL for pin verification is <youropenhaburl>/blink/<accountUID>. The easiest way to get this, is to copy the validationURL thing property:
(Images are not available anymore)

Maybe somebody has resolved this issue and can give me a hint. Many thanks

I’m facing the same problem with “Authentication challenge without WWW-Authenticate header” when I try to add a blink account. Seems like the API has changed.
