Oil filter housing leaking, can't get it to stop SB 273

Both but just a little from the bolt, more from the circumference as far as I can tell, oil drips all over. Last time I put it together it was not leaking, went for a half hour drive, came back a little drip maybe a couple of drops. Next day started the car backed out of the garage and massive leak??? As the car warmed up seemed to be less leaking happening. Maybe a crack but you would think as it warmed up it would leak more!!
