What am I doing wrong?

Ive fished for striper every single day for like 2 weeks on the Great Bay off the Piscataqua River and can’t get a bite for shit. I’ve tried every soft and hard plastic as well as frozen mackerel. I can not catch shit. I go mid day/evening most times. I fish off my dock or off a bridge. What do I need to do differently? When should I be going and what should I be using? Everyone else is ripping striper, this bay is flooded with them but none of them want to bite my shit
