On FreeBSD installation/upgrade may take significant time since all dependencies are built from ports and compilation takes a lot of time.
To check the status you may log into the server by SSH and check if 'autoinstaller' is running. Also, 'tail -f /tmp/autoinstaller3.log' will provide you with current status.
