The name <server name> already exists

I tried to add a host to a cluster but I typed the wrong password. Now when I tried again to add the host it gives me the error

The host is obviously nowhere to see just yet so probably just managed to get into the database but that is pretty much it ..
Anyone knows how to remove that host cleanly so I can re-add it ?

One of those moments where you really feel stupid
You have one. Use DNS.
