School network, nexus 6p keeps trying

My new Nexus 6p won't connect to the WiFi network at school, a WPA2 PSK network(802.1x EAP). It only says "Trying to connect..."("Verbinding maken" in Dutch). I think this will be a common problem, so that's why I am asking it here. Groetjes, Arend-Jan PS: Yes I have got the right ID and password.
