I think this is a pretty big leak, especially 170BB deep. When you c-bet into 2 opponents on an AAx board, you're range is going to include a lot of Ax hands. You should not expect opponents to bluff raise you on this board often, especially not with a pot raise size. I would expect that against most opponents you will be up against 88 or A8 very often here. Once you call the pot size raise, you have basically announced that your hand is an A (with likely 2-3 overcards to the 8) and your opponent still choose to pot it. When your range looks strong and your opponent still chooses to bet, you're pretty rarely getting bluffed. Sadly, this is a fold on the turn.

You have enough Eq to jam flop or turn, even if he has A8 or 88 only.

In my opinion your problems start with your way too large cbet.

Thank you very much for your insightful view of my hands

I would check flop. What's the point of betting? Then reassess the turn and river
