My iPhone doesn't connect to Whatsapp at the school's Wi-Fi?

When I open whatsapp on my iPhone 5 in school using the school's Wi-Fi, whatsapp won't connect! It says connecting and then no connection and again connecting.

Try using your phones's data network/ connection

Probably your school Wi-Fi has Firewall Restrictions, have you asked anyone else if whatsapp works on their phone with the school Wi-Fi?

Your school probably blocked it.

( the connection to the servers of Whatsapp.)

Friewall rules are blocking the application.whatsapp.use your own data. Don't connect to the Wi-Fi
