Problems with remote connection on vncserver

Hello. I tried using this tutorial: https://www.digitalocean.com/community/tutorials/how-to-install-and-configure-vnc-on-ubuntu-14-04 to make a vnc server on my dropler. I did like in the tutorial, everything worked. vncserver has started but now I have a problem. I put it on default: sudo update-rc.d vncserver defaults but even after reboot I still get the console on console access, but this isn’t my main problem. When I try to connect to my dropler with remote desktop (integrated in windows 7) I got an error (Remote desktop can’t connect to the remote computer for one of the reasons: remote acces to the server is not enabled the remote computer is turned off the remote computer is not avaible on the network

Also, when I try to connect with Putty, I got an error (connection refused). Can someone help me with it? I just don’t get how to make this work. Thanks.
