Cant even rember if it ever worked once actually… I might lose connection because of hick up of the game server, or my ISP resetting the line every 24 hours, anyways… my internet is backup in seconds and Diablo 4 cant reconnect , the game wont even complain , it will just sit there and hang on the reconnecting screen and then drop back to bnet desktop. My suggestion would be to poll the network adapter more cleanly and also checking for changed ip.
Im interested if this “feature” even works for ANYONE… reliably? Let me know.
Im guessing this is a game client problem more than a BNET app problem but well who knows… im not aware of the intrinsic mesh of dependencies in that regard.
