I play on the European servers and have the same problem every day:
In the morning I can play smoothly for hours and there are no queues, when i start a new game. Then in the early afternoon I am removed from the game and after logging into battle net the message appears: Authentication failed. Please try again.
I can’t get into the game all afternoon/night. There are short queues but at the end I get again the message: Authentication failed. Please try again.
The next morning the same thing repeats itself all over again. Playing until about 1pm and then I can’t connect to battel net.
I have already tried everything listed on the forums. Also the instructions from Blizzard link DNS flushing, …
Maybe someone can help me? Thanks a lot!
