Try making a connection test with your 3DS,if It fails,it’s likely to be a problem with your network.And if your connection works fine,check the server status if it’s working in this website:

It’s on my Wii U tho

SSSL does not support Miiverse posting or the Miiverse app, as they both are unaffected by the SSL bug.

In order to use Juxtaposition on your Wii U, you must set it up with Aroma custom firmware. Don’t worry, it isn’t hard.
