do not start the game sky3ds cycling through all your game then it will go back to the first game then again cycling through the game you want to play online then start the game
i have try some few test ... tested .... i think the sky3ds do not like to burn write 1 game online game that i no for sure is not the online header is the sky3ds the card it self Disk Writer not working online properly
so that why you need to
burn write at least 4 game or more game in to the micro sd card with the online game you want to play
do not start the game sky3ds cycling through all your game then it will go back to the first game then again cycling through the game you want to play online then start the game

it appears that people with either public headers, or multiple headers, are getting blocked with this (or similar) error.
no this no so far i did all the test .... tested .... this
Error Code 002-0123 is not a block error it mean you do not have the online header in you game so you can not go online Error Code 002-0123
