No internet connection - lightroom

Hi guys,

My lightroom is saying I have "No Internet Connection" even though my phone in connected to the internet and working fine. I have just bought a new Iphone and have changed all of my information over from my previous iphone and everything is working apart from my lightroom app..not sure if the new phone is the problem but it seems very strange. If i go onto the web version of lightroom it works fine. I have tried uninstalling the app and restarting my phone but no luck. I am now at a total loss on what to do... If someone could help me out that would be much appretiated. 

Thanks
