I'm logging in fine, but my friend is unable too. It kicks him out just after seeing the news. He's getting the same issue a number of other people are right now. I'm commenting here because the the only error he can see seems to relate to a certification.
His documents log.txt file shows nothing, but his _launcher.log shows: [17:56:23] SecureStreamSocket::ReceiveBytes(): [W] Connection to the game was closed before calling this method![17:56:23] SecureStreamSocket::SendBytes(): [E] Error code: 10053[17:56:23] Chat: [E] Worker.Run() SSL_ERROR_SYSCALL: Some non-recoverable I/O error occurred. Check lines above that[17:56:23] Chat: Disconnected[17:56:24] Proxy::Run(): [E] Disconnected from game[17:56:24] PreGame: Disconnected[17:56:24] World: Disconnected[17:56:24] Matchmaking: Disconnected[17:56:24] Borderline: Disconnected
Its likely related, but I honestly can't say for sure. If this is a proper cert, anything I artificially generate would be invalid so I can't really test.
I'm using windows 10, and on windows 7 (if this matters)
