Registration Expires Automatically

1

When I follow the following steps:

  1. Open the login page of some realm.
  2. Click on register to open the registration page on a new tab.
  3. Then on the registration page click on login to open the same login page in a new tab.
  4. Now you have 2 tabs with login and 1 with register.
  5. Back to the register tab and click on register.
  6. The page refreshes and shows: Page has expired

This is the only scenario I managed to catch that shows this expiration page. But it happens randomly. I want to prevent this expiration regarding the opened tabs. How can I achieve that?

Notice that I increased the login time out and login actions to 1 day, but the problem isn’t related to the expiration time of the login session.
