Nah you’re not missing anything from the normal process here, however that network does not support bootstrapping custom built Vaults or Clients. Its Limitation pt 3 which restricts Vaults which also does the same for custom built safe_core.
Users can’t run their own vault. To allow developers and users to use the SAFE Launcher API1 without losing data or seeing performance issues, MaidSafe manage all the network nodes. This network is client-only and uses a unique private network name.
Once TEST-8 is up this Tuesday, this same process should work fine to connect to the test network. Sorry about that.
