Front derailleur not shifting to largest cog

It's a 21-speed with shimano tourney fd.
For some reason the chain stopped shifting to largest cog, and then I decided to tighten the shifting cable which helped a bit but it seems the mech itself wouldn't move far out enough, causing noticeable chain rub. Btw, the cable is almost stiff at this point. I also loosened the high limit screw, which didn't do much.
It also seems placing the derailleur cage parallel to the the outer ring, causes the chain to rub when on a lower ring. It's a fairly new bike.

Front derailleurs rarely go wrong, especially when new, so It should be an easy fix. If you can't fix it, then take it back to the shop.
Note: A new cable normally sorts out most gear shifting issues.
