Error 517 appears when Roblox backend services reject or fail a request — common during patch rollouts, experience updates, and traffic spikes. Check live Roblox status before clearing cache or reinstalling.

517 vs other Roblox HTTP errors
517 sits alongside 529 and 524 as a server-side response. If many players report 517 at once, wait for Roblox to recover. Isolated 517 on one game often means that experience's servers are overloaded.
How to fix step by step
- 1Check live Roblox server status on Oracnoos.
- 2Wait 15–30 minutes during confirmed outages or patch windows.
- 3Leave and rejoin the experience — avoid rapid reconnect spam.
- 4Try Roblox on web vs mobile/desktop to isolate client issues.
- 5Clear Roblox cache (mobile: reinstall; PC: clear temp Roblox folders).
- 6Flush DNS and test another network if status is operational.
- 7If only one game shows 517, check that experience's social channels for maintenance.
How 517 differs from related codes
- Error 529: Roblox returned an HTTP 529 or service-unavailable style response during join or API calls. (server or client)
- Error 524: Roblox received an invalid or timed-out HTTP response from its backend. (usually server-side)
- Error 279: Roblox could not establish a stable connection between your device and the game server. (server or client)
