2.5 Side Scroller - having issues with camera need some advice!

I am rather new to UE and I decided to make a 2.5 scroller I can not for the life of me figure out why when I go through the level the camera comes to a stop but my pawn can continue running indefinitely until it hits the edge of the landscape. The camera only seems to be following for a short distance compared to the size of the landscape, it can move X -1500 to X 9000. As I mentioned the landscape a distance the pawn can continue to travel after the camera stops is roughly +80k in X. This also effects where I can spawn my character also, seems that -1500 off the center of the landscape is the furthest it will work.. if anyone could give me some advice or if anyone knows a fix for this I would greatly appreciate it.

Thank you
