There is always a cloud in every silver lining.

Question

Answer

You shouldn't trust the good vibes all the time. Because something unexpected might happen.

Answer

It's hard to tell if you have deliberately inverted the standard phrase or not.
It's possible to invert it as you have - to suggest that every lucky coincidence has some downside. BUT - since it is a play on words, you have completely lost the significance of that play on words, so I would suggest that it would not be a good idea to change it.

Answer

Isn't it rather: every cloud has a silver lining?
