Slot booking restriction

You have exceeded the limit to view this page. I am viewing the same message while appling for F1-Visa from India.
I saw this message 4:30 in the afternoon yesterday and tried to login 2-3 times after that.

When should I try to re login today 5 pm or 24 hours from the last time I tried to login( today morning 4:00am) like does the clock reset every time?
