Help me troubleshoot realVNC clipboard not working with Ubuntu instance

Using RealVNC on my windows machine to access the ubuntu vm. I have modified the preferences/settings on VNC to allow clipboards to move between the machines, but it still doesn’t work. I was wondering if this a growing pain from the new implementation of VM’s in fangtooth? Or am I just too noob to figure out what’s wrong and in need of troubleshooting help.

For anyone in the future with similar or less experience than me. I use realvnc to connect to my ubnuntu vm. Then in the ubuntu settings I enabled remote access and disconnected realvnc before reconnecting to the vm with RDP using the local ip address of the vm. Now copy and paste is working.
