Summarize your bug I get this error message when a try to log in the launcher. It worked fine before, but since march 28. just won't let me in. Tried to clear cahce, repair and reinstall, none of it helped. Other launchers (and browsers, donwloading etc.) are working fine so it is not my internet connection. At least not on my end.
How often does the bug occur? Every time (100%)
Steps: How can we find the bug ourselves? Good question. Check (log-in) servers maybe?
What happens when the bug occurs? As mentioned before.
What do you expect to see? That i can log-in and able to play my games, maybe?
