Hi! I just made a pretendo account for me and my sister and we both have nat type B, for some reason we are unable to join the gathering hall of eachother. We can make a online session but never join one. We are both trying to play just a single room away and theres no issues with the router or connection otherwise as we can both play local play just fine. any help would be appreciated as I tried scouring for a solution but nothing so far has helped as far as I could find, I also rebooted the 3ds systems, router, and tried reinstalling nimbus as well with no success.
