Error Code 015-5015 when opening up Juxtaposition

I have recently been kept getting error code 015-5015 when opening up Juxtaposition on my 3DS. Juxtaposition did work a few weeks ago but now it doesn’t. And yes, I do have a stable internet connection so I don’t really know what the problem is.

I Have The exact Same Issue!

So what y’all wanna do is reinstall Nimbus. To do that, delete the Nimbus app in system settings data management, and then manually install Nimbus by following this guide. After you finish reinstalling Nimbus, resign into Pretendo, and you should be able to load Juxt.
