I was walking through the creation of community in Trailhead. It asked me to name the domain for the url"cloudkicks". I did so, but when checking avialability, it said that was not avilable. I appeneded my name to the front and it worked successfully. However, it will not let me complete the challenge becasue the name does not match. Any suggestions? I tried starting over, but it seems to keep bring me back to that particular community.

I am trying to access one of my Customer Community pages and I can not access it from the Header bar. I can access it from SF "Communitites" "All Communitites" I can access "Mannage" and Builder from there. 
Why do I get the above error when trying to access it from the Global header area?

Any help greatly appreciated.
