Just started over the last few weeks but I have been getting small disconnects during HotS only which are happening while just in the main menu.
The game will tell me I am reconnecting which will last for around 5-10 seconds Then bring everything back. While happening it stutters my whole network. Twitch stream freeze for the 5-10 seconds, I cant talk or hear people in discord during the time frame either.
Again it only happens while logged into HotS and my net has no other issues until I am logged into it.
