How to pass CAS authorization on the QIWI website?

Question

Qiwi

I do authorization on the QIWI website. You need to pass authorization through CAS.
New cookies should come, but they don't! The 3rd Request cannot be done correctly. I don’t understand what I’m doing wrong, I tracked requests with a sniffer, they go exactly the same. Help who can, I've been fighting for a week, I don't understand what's wrong.
