Leak at filter housing

I fired up my 4000D today after replacing the piston rings. I have a terrible leak at the oil filter housing. I have successfully replaced this filter before as well as the one on my 5000D. The only difference is that I used the filter that came with my parts kit (Fram) and I have always used a NAPA 1279. The housing feels snug against the block, the gasket is flat and in place. Anybody fought this battle and won before? I tried three times; removing the housing,cleaning the gasket and surfaces and re-installing. I apparently am making the same mistake each time.
 

I have had to start over with those. If it passes the flat face test, try getting the screw started, then get the gasket, then the can in place with a little twist. This should get it aligned/seated without pressure. Then, holding the can firmly against the block, tighten the screw.
