Proper shutdown of astroprint?

When I want to turn off my astrobox, I do it via the menu in the upper left corner of the screen. Usually it happens without problems but sometimes I get a message that there was a problem starting the shutdown. Then I am left hanging with no options. There is a button that says something like try reconnecting but that never happens so all I can do is turn the pi off which seems to lead to more problems the next time I turn it on. How can I avoid these issues?
This happened last night and I currently cannot connect via the internet but I can do everything I need via the local connection. I really would like to avoid these issues but they seem to keep occurring.
Thanks for your help…
