[HUMMINGBIRD] When cache option is on protected page just keeps loading

When cache is OFF in Hummingbird my page which is protect by password works ok – I enter pass and I see the content.

When cache is ON in Hummingbird same page which is protect by password does not works ok – I enter pass and page just reload.

I try to HB -> Cache -> Exclusions for that page but same issue exist.

Any help on this?

Thank you
