I too am experiencing this same issue (I’ve been playing since a day or two after Overwatch 2 launched without losing connection to the server that is until the past day or so).
I remain hopeful that tomorrow’s live maintenance may resolve this problem!
after the maintenance and update, my overwatch actually logged me in. Then later today I tried and i’m back to “Game server connection failed… retrying”
I hope you all are in the same boat as I am but for the past two days, I’ve been able to play Overwatch 2 (both quick play and competitive modes) without a single disconnect from the server.
I’m not sure if Blizzard updated their servers recently or if it was because I went from an Ethernet connection to Wi-Fi (maybe it was a bit of both), but ever since then, not a single disconnect!
Best of luck to those still attempting to get into the game without disconnecting!
