Server not Start

After give the command **appollo build start** on command prompt it only display **"No instance available at the moment. Waiting for one to be free..."** wait for 2 hrs. nothing happens.
Please check the issue...

Start by reproducing the reported `appollo build start` command and inspect the CLI entry point that handles `build start`. Determine why it remains at “No instance available at the moment. Waiting for one to be free...” and verify that the command either starts successfully or reports a useful failure instead of waiting indefinitely.
