MySQL Workbench failing on TCP/IP over SSH

Going NUTSO - spent last 2 days trying to figure this out...

I can SSH to my provider (bluehost.com) and access my MySQL databases with "mysql" commands using login credentials or using SSH public key authentication.

But connecting using Workbench using TCP/IP over SSH (latest version and tried 2 versions back) results in:

Failed to Connect to MySQL at 127.0.0.1:3306 through SSH tunnel at mygifXXXX@mygiftisasong.com with user mygifXXXXXX

Lost connection to MySQL server at 'reading initial communication packet', system error: 0

The Workbench log:
12:57:51 [INF][ SSH tunnel]: Opening SSH tunnel to mygiftisasong.com
12:57:52 [INF][ SSH tunnel]: TunnelManager.wait_connection returned OK
12:57:52 [INF][ SSH tunnel]: SSH tunnel connect executed OK
12:57:52 [ERR][sshtunnel.py:notify_exception_error:235]: Traceback (most recent call last):
File "C:\Program Files\MySQL\MySQL Workbench 6.3 CE\sshtunnel.py", line 350, in accept_client
sshchan = transport.open_channel('direct-tcpip', self._target, local_sock.getpeername())
File "C:\Program Files\MySQL\MySQL Workbench 6.3 CE\modules\wb_admin_ssh.py", line 165, in wba_open_channel
raise e
ChannelException: (1, 'Administratively prohibited')


I even tried ssh remote port forwarding from the server to my local machine per https://stackoverflow.com/questions/29462656/yet-another-lost-connection-to-mysql-server-at-reading-initial-communication-p but get the same error and using the locally mapped port in Workbench but still can't get past:

Failed to Connect to MySQL at localhost:54321 with user mygiXXX

Lost connection to MySQL server at 'reading initial communication packet', system error: 0

What could Workbench be doing that is "Administratively Prohibited" that the SSH session isn't doing?
