my wifi is blocking some apps on my iphone?

yeh so basically i have this app on my phone, Tinder, everyone is using it these days, and it only seems to be not working in my own home. when i use 3G it works, when i use any other wifi networks at these uni or my mates it still works. just not through my home wifi? :S

i have to switch wifi off to reply to people on it and its really annoying and also wasting my internet usage... any suggestions on why this is?


thanks
