Ok, I'm not sure if I'm having the same sort of problem, but I just made a new profile on my computer and got Minecraft on it, now when I go on my old profile to play 5 servers don't work and give me this message. How can I fix this? BTW, these are servers like Arkham (which might just be down), a few small servers, and a few large servers like MultiCube and Hypixel.
