Can't connect zlib error

Can't connect zlib error

Pocketcloud worked great on my ipad connecting to my mac , then i reinstalled my mac os and set everything back up. however, now when I connect I get the error,

Vnc session disconnect 01vnc: zlib error

However other vnc apps work to the machine from my ipad, and apple screen sharing work fine from another mac to this machine. I even uninstalled PocketCloud and data and rebooted my iPad and that the not resolve the issue but like I said other VNC apps on the iPad will connect to this machine.
