I'm receiving the error "A socket operation was attempted to an unreachable host. (10065)."

This error means that a socket operation was attempted to an unreachable network. It usually means that the local software (in this case VNC Viewer) is unable to find a route to reach the remote host (VNC Server computer).

It could suggest an underlying network issue, or is more likely simply a configuration issue. Please see the related "Connection Timed Out" article, for troubleshooting steps.
