Toilet Leak - on connection into tank

I noticed a small leak in my toilet. It only leaks when the water is turned on. Initially, I thought that the rubber ball ck gasket inside the tank had worn out but I replaced it and there is still a leak. What parts between the wall and the tank might be causing the leak? Thanks in advance for the help.

Is the nut (holding the supply line to the fill valve) at the bottom of the tank leaking?
If that's it, wrap 2-3 flat wraps of teflon tape counter-clockwise (because it's upside down) on the threads, and then tighten the nut onto the fill valve.
Good Luck!

Install a new supply line, use a braided flex supply, if you have not replaced the supply line yet.

The old supply line was affixed permanently to the shut off valve so I ended up replacing the shut off valve, supply line and ballcok. This seems to have fixed things except now I have a small drip in the shut off valve on the connection from the pipe to the valve (compressor connection). Maybe I should just tighten it more although I think the instructions warned against over tightening.

Shut water back off, back off nut and remove valve.

Then take a small amount of teflon thread sealant and apply a minimal amount on the front side of brass ferrule on copper pipe.

This is the point of contact where water can leak; doping the threads on compression valves is not where the source of water is.
