Guild Wars 2

i had this issue the past 2 days aswel (windows 8.1) tried all my 10 characters and couldn’t get in any one of them. Sometimes i couldn’t even connect to the login server

When i got my monthly chest on one of my low lvl characters i forgot to open it. The next day i deleted this character ( and thus forgot to open the chest). Is there a way to get my chest back? Or could you make something so that your chests can be opened account wide?
