Fortnite Rocket Racing is quite popular among players, perhaps even too popular. Whether the game is down or if it's your connection, I'll let you know below.
How to fix the queuing failure 208 error in Fortnite Rocket Racing
The launch of Fortnite Rocket Racing is attracting a large number of players to its servers, resulting in numerous issues. Many players are getting kicked out of matchmaking games due to the Epic Games servers' inability to handle the high player volume.
In order to determine whether the issue is on your end or the game's end, I suggest checking the Epic Games server status on their website or referring to other platforms where players may have reported a similar problem:
If the servers are not operational or if players are reporting an error similar to the queuing failure 208 error, there is not much you can do except wait for a while, as this issue is not on your end. If the servers are operational and fellow players have not reported any issues, I suggest troubleshooting your internet connection and then restarting both the game and your PC before attempting to play again.
