Unexpected disconnection after downtime

I've never had any problems before but as soon as we came back from downtime I'm getting an unexpected disconnect every couple of seconds and booted back to the login screen.

Same here.

I'm having the same disconnect issue. After the update today (09-20-2018), I cannot log into my delve character. I keep getting disconnected with the message: "An unpected disconnection has occurred." Oddly, I have no problem logging into my standard league characters.

Same issue hear is their any fixes to this i validated my game files in steam and still having the disconnecting issue
