It sounds like they don’t want to play with you. Please understand that we cannot force people to play multiplayer with other people.

no its not that coz a moderator tell me that the gpu go crazy when i connect that’s why he banned for other host and ask me to download new citra and install and i did but he kicked me from the last host that i can connect on no.912
