Error code 022-0602 whilst trying to connect to Juxtaposition for the 1st time

Hi! I’ve just made my Pretendo account and set up Nimbus on my New Nintendo 2DS XL. I’m Canadian. I tried connecting to Juxta not long after making said account. After the beginning setup, I got error code 022-0602. Looking it up on the Pretendo Website, I got “Unknown cause.” and “Unknown solution.”, but the website knew it was 3DS-related.

I don’t own any 3DS games that Pretendo supports and Inkay refuses to work on my Wii U and I don’t own any games that support SSSL. Any help would be appreciated! Thank you so much!

Can you be more specific here?

I have never seen this error code before…

Can you try re-installing Nimbus from Universal Updater (no need to uninstall, just re-install) and then open up Miiverse?

Is this still an issue?
