I suddenly lost all my PH streak although I had been visiting daily! And this happened after months. First, it stopped showing my profile in the list and then suddenly PH reset it to 0 one day. So, I don't even bother with it now.
If you miss a day on Product Hunt, unfortunately, there is no way to recover your daily streak. Your streak will reset to zero, and you will need to start again from the beginning.
