Cannot connect, error No.015 and 102

GameCube. Made myHL account, same serial and access key as sticker in my game, followed gcn set up tutorial, use same password as myHL account, doesn't get online.

I've been trying for half an hour rereading the guide and reattempting. One time I used a wrong password and got past the loading screen where you can move with analog into another error screen that was error 102.

Is the ip address in the guide wrong? Are these servers even real? Is this some cruel joke. I was never able to get my game online as a kid, was so excited to see that this service exists, yet once again I am denied online mode.
