Hi @Aengus Rooney and @Tamas Bihari,
I just ran into the same issue. I tried to deploy with two different unique stack names and both times I got a failure during cbdinit. For giggles I tried again but this time removed the non-alphanumeric characters ('&' and '*') from my password and it succeeded. Seems like there is an implicit character set limit on the password. Would be nice to either remove this limit [preferable] or at least make a note on the form that only alphanumeric characters are acceptable.
