Multicraft Daemon error?

I installed Multicraft on my server today, but the Multicraft Status always says there

Authentication failed (code: incorrect authorization)

And if I want to set anything on my Minecraft server it says

Authentication failed (code: incorrect authorization)

What do I have to do so that I can use Multicraft?

I have a few more screenshots here:

It's on the side…
