I am unable to get the Marketplace or Realms to load. It keeps telling me to check my internet connection, but my Switch is connected, and I'm able to play other online multiplayer games with no issues. I've also done things like remove the Switch from the dock and bring it closer to the AP and changing my DNS settings.

The game can load my Xbox account (and brings up my handle), but that's all it can access.

There's no mention of any downtime on the official Twitter or wide-scale outages on other third-party uptime monitoring websites.

I've also tried archiving the software and reinstalling, since this fixed a bug of uploading a new map to a Realm a few months ago, but that did not work for this issue.
