Binding Amazone Echo Control login problem

Hey there,
I have a problem with the Amazone Echo Control Binding.
After weeks it isn’t possible to login in my account.
I tried it over this link:
http://openhab:8080/amazonechocontrol/

So far so okay, but after type in the OTP. I getting this problem:

Invalid redirect to 'https://www.amazon.com:443/ap/forgotpassword/reverification?arb=7f99f862-840a-41a4-b687-

Try again

What can I do? I already did a reinstall. I have the version 2.5.7 installed.
