Damaged strawberries - Could you help me identify the problem?

Some of the fruits from my strawberries in tubs have a somewhat glossy look to them, and the little leaves around them look like they are turning reddish.
I let one of the fruit develop and one side turned out waxy, somewhat grey and definetely unhealthy (sorry, I did not take a photo of that specific one, which would probably have been more illustrative than the one I am posting).
is this some kind of fungus?



Also, a few more fruits show damage or even rot, even if they are not touching the ground directly. I suppose that might be some kind of aphid or beetle?




Thanks for any advice and/or suggestion on how to contain the problem
