If Roblox won’t let you join a game on a phone or tablet, first check whether the problem affects one experience or all of Roblox, then check Roblox’s service status. An error 524 usually points to access or private-server permissions; error 266 points to a connection timeout. After identifying the likely cause, check your device and app, then try another network.
Start by narrowing down the problem
Notice whether Roblox opens normally and whether you can join other experiences. If only one experience fails, its server or access settings may be the issue. If all experiences fail, check your connection, app, device compatibility, and Roblox service status.

Roblox recommends checking its Status page when you have trouble joining or playing. Status changes over time, so check it while the problem is happening rather than assuming there is an outage.
Use the error message to choose the right fix
| What you see | Likely direction | What to check |
|---|---|---|
| Error 524 or a private-server message | Access or privacy permissions may be missing. | Check whether the server owner invited or allowed your account, whether you meet any membership requirements, and whether the server is available. |
| Error 266 or “Your connection timed out” | The client could not establish a connection in time. | Try another internet connection; restart and reopen the app; check your device’s date and time. |
| No clear error, but one experience will not load | An issue with that experience or its server is plausible. | Try another experience and check Roblox Status or notices from the experience’s creator. |
| No clear error, and no experiences load | A broader connection, app, device, or platform issue is more likely. | Check Roblox Status, test another network, and verify your app and device meet Roblox’s requirements. |
If you see error 524
Roblox says error 524 typically means you do not have permission to join a specific experience or private server. Check the server’s invitation or member list and the experience’s access settings. If you believe you should be allowed in, ask the owner to confirm your account is invited and that the server is available. Roblox’s Error Code 524 guidance covers permission-related checks.

If you see error 266
Error 266 is a connection timeout, not the same as a permission error. Roblox associates it with connectivity problems such as low bandwidth or internet speed. Try another Wi-Fi network or switch between Wi-Fi and mobile data, if available. Restart your device, force-close and reopen Roblox, and check that the device’s date and time are correct. Roblox lists further mobile troubleshooting in its Error Code 266 guidance.
Check your phone or tablet and the Roblox app
Roblox’s published mobile requirements specify iOS or iPadOS 14 or later, or Android 8.0 or later. Android devices also need OpenGL ES 3.0. The requirements page gives a minimum internet connection speed of 4–8 Mb/s; Roblox does not state a publication year for that figure, and it is not a guarantee that every connection or experience will work smoothly. Roblox suggests trying Wi-Fi if cellular service is causing problems. Check the current Roblox Mobile System Requirements for device details.

Test the network before reinstalling or changing settings
Try a different Wi-Fi network, or switch between Wi-Fi and mobile data where available. If Roblox works on one connection but not another, that points toward the failing network rather than a permission setting for the experience. Weak or inconsistent wireless service and slow connections can prevent Roblox from connecting; the General Connection Problems guidance lists connection issues among possible causes.
Make one change at a time and retry the same experience. That makes it easier to tell whether the issue is tied to one experience, your app or device, or a particular network.
