PocketCloud Pro Not Working, Old Free Version is Working

I don't understand how to setup my connection. I just bought PocketCloud Pro to install on my iPad2. PocketCloud Free is still working on my original iPad 1. The Free version does not work on my iPad2, it gets the same message.

When I try to connect using the newly installed version (2.1.217) on my iPad2 I get:
"Error: VNC: authentication failed: 1"

I'm not sure what to enter for Host and what I see on my iPad 1 does not make sense. Is there anywhere I can see what my "Host" setting should be; currently only showing my computer's name.

Do I need to disconnect the connection that works to get the new one to work.

I have search your online databases and FAQ and cannot find anything related to "VNC: authentication failed".
