Using forge 1.11, cant log in

I am building a custom map on version 1.11.0 with the mods worldedit and OptifineHD along with the ItemBound Resource pack. Well, I was until this new laucher arrived. At first I thought it was epic but then when I chose the forge version and clicked play, instead of loading, the game showed me this message (shown in picture below). I'm not sure what it means, only that it wouldn't let me play the game... maybe the new launcher isnt compatible with forge or mods??
