When I use the Update option on the Shovel Knight main menu, the progress bar advances three times, then returns the following error:
Error Code: 005-6710
An error has occurred.
Please try again later.

My Internet connection is working properly and my 3DS is correctly configured for WiFi internet access. I don't have any blocked ports on my end. Nintendo support says this:
An error occurred while attempting to connect to the Nintendo eShop.
However, the eShop doesn't seem to be down. A Google search turns up nothing regarding this error. Besides, if the game is already up-to-date, it shouldn't be returning a weird error message when trying to update. Any ideas?
