Can't open Tickets

I got a reply on my Ticket, but I can not open it. I get a message saying :

“Something went wrong on our end
An error has occurred. This may be a temporary error, so please try again later.”

Error code: 31a5333e-0e4d-4e34-ad83-303a84ffd952

To confirm, have you tried looking at the following page to view all open tickets in Blizzard Support site:
