I'm replacing the toilet connector hose because there's a leak from the bowl. I've tried to remove the old connector hose but the metal piece in the pic will not detach. It spins when I use a steel adjustable wrench but no movement otherwise.Any ideas on how to get it off?

The toilet connections shown depend on rubber gaskets to make seals. These seals likely need replacement. In addition, I see that PTFE (white colored) tape was used. It should not be used for these fittings (or any compression or flare fittings), and can cause leaks.
Disassemble the connections. The top leak is likely caused by the washer (inside the toilet tank) not being seated correctly. The gasket should have come with the replacement fill valve. The tank should be cleaned at the location where the gasket sits. I can't tell for sure, but the nut holding the valve onto the tank looks a little bit undersized. It should completely cover the hole in the tank.
The metal flare tube also needs a washer in order to mate with the fill valve. This washer should be replaced. I would tighten it hand-tight plus 1/4-1/2 turns. In addition, the nut should be cleaned of the debris visible in the photograph.
Another reason could be that the tank was cracked. Sometimes, hairline cracks are very difficult to see, but are able to produce leaks.
that is a compression fitting,the nut is against the wall plate.using 2 pairs of adjustable wrenches,use 1 wrench to hold the valve(holding the valve just under the outlet hose)use the other wrench to loosen the nut.when done the valve will pop off leaving the nut and a brass ferrule.carefully remove the ferrule with pliers(wary not to crush the pipe,grip the ferrule and twist back and forth while putting pressure in a forward,pipe opening,direction)remove the nut,then replace with new valve as above,in reverse

In the "old days" there were a ton of stop valves installed that had the flex supply line integrated into the valve, i.e. all one piece. Thankfully, they started disappearing from the market. Now we are seeing Chivese stop valves with integrated flex supply; I suspect yours might be one of those.
I suspect that to replace your flex you will need to replace both the valve and the flex. However, you say there is "a leak from the bowl", which shouldn't have anything to do with the supply flex because the supply flex goes to the tank fill valve, not the bowl.
