Default cant connect to play store

hey guys im using the latest purity rom but i cant connect to the play store my wifi icon is red, ive tried other peoples wifi and its still the same but my home wifi works perfect on my tf300 and htc one, ive tried clearing caches and all kinds of reboots and even reinstalling the rom but its still the same, so i thought i would try a different rom so i tried dirty unicorns and its still the same, whats the best way to fix this
