Did you try restarting minecraft? If you have ReAuth installed (you probably have it if you use MYM launcher), you can click multiplayer and look at the top left corner of the screen. If there is green mark, you are logged into mojang servers, otherwise you have to press re-login to log into them.
Very simple. either your using a cracked client, a cracked username, or the mojangh servers are down.
Trying right now. EDIT: Tried, didn't work. [DOUBLEPOST=1479695078][/DOUBLEPOST] Nope, nope, nope.[DOUBLEPOST=1479695108][/DOUBLEPOST] No, just tried. It had a longer "Logging in..." screen then usual, then did the same message. Also what's weird is that I can log into AG2 server fine... AND: I use the direct connect IP. agrarian.mineyourmind.net Maybe if I connect to the hub then try to join. But I don't know the hub lobby IP EDIT #2: I tried the MyM Launcher and it works. I really prefer the Curse launcher but I'll start using the MyM launcher. Thanks for the help!
