Seems like Nintendo absoluetly didn't care about their new online services. But this is something i was actualy excepting that. Anytime I try to use online service in Nintendo videogames it becomes a (how unexceptably) failure, this has been a major problem for me since a Nintendo 3DS arrival. I was able to use internet in my N devices but never able to play online. Time passed and i figured out the problem is in my Wi-Fi router, yet still, Nintendo should be responsible about how wacky are their services, because after what i found about my router settings, there were no any firewall blocks, dmz, etc.. I was checking that many times! I used the same router in DS and Wii era, and online worked fine. Now i do really wonder that I yet still never found anything about this new Switch error code. I cannot be only one who have this problems with online multiplayer gaming.
