If you search the Nintendo Support page and get no results for an error code, it is vital to submit the error code through the email listed above. It is best to include information like the make and model of phone you are using, the OS version you are running, and what you are doing in the game when you experience the error. This gives the developers the best chance of replicating the code and solving the problem quickly.

Mario Kart Tour Heavy Traffic

Some players are getting a login failure message that will say, “The servers are experiencing heavy traffic. Your log-in request will be processed in the order it was received”. This is more easily explained as launch day traffic just being a bit higher than the servers can handle. When you try to log in, you get placed into a queue. The issue appears to be compounded by people not being moved out of that queue.

The best solution here is to try and log in again, and if that doesn’t work, then let some time pass before you attempt to log in. With lots of people logging in at once, there is just too much traffic for the system to handle. After maintenance tends to be a common time for this to occur, as people rush to get back into the game again.

To find out when a maintenance occurs, and try and avoid logging in at these times, it is best to follow the Mario Kart Tour Twitter account, as they will tweet out the schedule for any maintenance that is planned.
