115-3056 when attempting to use Miiverse functionality in a game (Local Server)

Technical Discussion
1

I’ve been working on a project to update Mario vs Donkey Kong Tipping Stars to the V2 libraries, but I’ve also been doing general testing with the Datastore rework. I’m noticing that a few games that use Datastore also rely on Miiverse. Unfortunately, I’m receiving error 115-3056 from the In-App Posting applet thingy.

This means that I’m completely unable to access online inside of MvDK:TS, locking me out of testing my server I made. Is there a known reason as to why this could be happening?

I’ll note that I’m not receiving any output from miiverse-api, so I’m assuming that it’s not even reaching the API to post anything.

Wanted to manually bump this issue because it’s still occurring. I’m not sure if any of the devs are familiar with this error, but it would be nice to at least know why this error is occurring.

Bumping this because I have a new symptom in my logs now. Every time I try to connect, I receive “error establishing server connection: [WinError 1225] The remote computer refused the network connection”.
