Recently, more than ever, I’ve been getting more and more issues with the game disconnecting and refusing to reconnect. It’s one thing when the game disconnects and then reconnects and wastes most of my turn, at least I still get to play my game. But it’s becoming painfully obstructive when the game constantly disconnects me in the middle of a ranked game and forces me to automatically lose instead of reconnecting me because I automatically lose a rank at completely random even though MY connection is very stable. Please fix these disconnect and crash issues, this game used to be fun and enjoyable to play, all of these bugs and disconnect issues just make it purely frustrating.
It’s unlikely it’s not your end, because it’s not a general problem (today at least (you should had seen the chaos the Titans bug produced but I digress)).
If it’s a mobile device: they often just disconnect anything that goes out of focus (to save battery) so check your app power settings etc.
Sometimes it’s the fault of ISPs connecting to each other, either the ISP for Blizzard’s datacenter’s or yours.
