Password Protected Page – When I enter password, I’m redirected to the WordPress login form

I have a page at https://sportysacademy.com/cfi/ when I enter the password for the password protected page, I get redirected to https://sportysacademy.com/wp-login.php?action=postpass with the error message

Error: The username field is empty. Error: The password field is empty.

Any ideas as to why that’s happening? I’m at a loss.
