Can kik work with wifi connection, or only the data connection?

When connected to wifi, it says connection failed and I need to connect to a data connection or wifi on my iphone 4s, and i am connected to wifi. But when I use my 4g it works. Any one else have this problem?

Wifi should work

I have an iphone 4s and it works when i only use wifi try double clicking the home button, holding the app and closing it, then restart your phone that should work!
