I know what he's saying. Its leaking from the spot where the metal goes into the nut. That's usually because the rubber "washer" isnt being compressed to create a seal. Cleaning it up may help.
did you try the line with the washer?
No thats a compression fitting. The inside of the pipe needs to be shaped like an inverted pyramid. This is assuming the hose end seal looks like a pyramid, most do. The valve looks like a standard hose bib style. Try a garden hose?
Looking at the pic its exactly what I was thinking. That valve isnt set up to receive that style hose. You'll need an adapter or a different hose.
