Game disconnects from blizzard every 2-3 mins of a game session start and doesn’t reconnect.
I have reset my router, set permissions to Administrated, reinstalled after manually deleted D4 folder after uninstalling.
All my games on steams/EA/Ubi work fine and zero stream interruptions, just blizzard constantly dropping me.
Nothing more fun then spending the first 2 hours of a new season just trying to get battlenet to work for more than 3 mins 
Any help is much appreciated.
This is happening to me. I just bought the game. Tried everything. Geforce 4080 super, 300mbps/20mbps hardwired, firewall troubleshoot, reinstall, reboot, and on and on. Game disconects after a few minutes. Sometimes just quits goes back to desktop. How annoying. Every other game works fine. So what is there to do?
Disconnect after disconnect after disconnect after disconnect !
I mean…really…what the…
Also getting constant disconnects. Sometimes within minutes of starting the game, and other times it could be hours into a session. Game often quits to desktop after disconnecting. Really annoying.
Having the exact same issue: no pattern to it, can happen when doing anything in the game including standing still in town (not afk).
This season is the first time this has happened so something must have changed Blizzard’s end 'cos nothing has changed this side.
It’s extremely frustrating.
This is happening to me far too often. I log in, pop a potion and an incense, start a ND, teleport to the dungeon only to be hit with “The game connection has been lost” and of course, there goes my potion, incense and key. They need to fix this, it’s at the point I don’t even want to play anymore.
