Honestly it doesn't sound like the OP is doing anything that would cause the aggression. Yeah, the temps and humidity are a *tiny* bit off, but not enough to cause issues with the snake regulating its body temperature.

I would chalk it up to stress just from being in a new environment. Even if husbandry remained exactly the same the snake would probably calm down within a week.

I would give him space for a few more days, then try offering a meal.
