ISP blocked all thing from battle net

hello
i tried to connect wow but the problem is that for sure ISP wont let me to connect wow. the question is , there any way to i skip this problem ?

Get a new ISP, or ask them to unblock it.

Additionally you could use a VPN if you didn’t want to switch ISP (if they aren’t willing to unlock battle net.) They would be able to confirm or not if they are blocking it and if so, why. If they are not, they could look into any potential routing issues or whatever may be at play.
