Error 429, which has an “Authentication Failed” message, occurs for some players when they try to play Roblox games. For example, one player described the issue:
“When I try to launch an experience from the (Roblox) website, 90% of the time it says error 429, and my settings won’t save anymore.”Players can’t access and play Roblox games when that error arises.
To resolve the issue, start by checking the Roblox server status to see if there’s a general server-side issue causing the error.
