Typically the issue where the login page refreshes without an error message stems from an incorrectly bookmarked link. Please try logging in using the URL below. Then make sure the link is bookmarked after successfully logging in so subsequent logins will work. Bookmarking the redirected URL (https://idp-awsprod1.education.scholastic.com/idp/) will typically cause a login failure.
Please give this a try and let me know how it goes. Thanks!
