In my opinion, Hera's weakness is her husband, Zeus. Whenever he cheated on her, Hera would either have revenge on her husband's mistress or she would do something else but as bad as having revenge. Although, Hera's sacred animals (peacocks and cows), too, could be a weakness.
BUT, Hera's biggest ever weakness must be Hephaestus. Since Hera is the Goddess of Marriage and Childbirth (there are a lot of Goddesses of Childbirth), her biggest weakness must be to have an ugly child. Hera either has a perfect family or she will be pissed. Hephaestus was ugly so Hera threw him out of Olympus, that's why he was a cripple.
The weaknesses and strengths and limits of Hera, Queen of Heaven, are not to be limited by human imagination.
