Keymaster can't post my key

Following all the steps listed in the Server setup guide, but when I get to the Keymaster and put in a name for my server, it takes me to a blank page that just says
" Cannot POST /k/keys "
Have I missed a step?
Or does the keymaster just not like me?

It’s been fixed, have no idea what has changed but I got my key now.

Now we can actually play the game together, nerd.
