188.8.131.52, when set up through my router, seems to work fine with every website I’ve tried via Chrome, but doesn’t work with the battle.net app when playing Heroes of the Storm.
This battle.net forum indicates others are having the same issue: https://us.battle.net/forums/en/heroes/topic/20764136654#post-3
Switching back to Google’s DNS lets me connect again.
