On screen: Your connection timed out. Check your internet connection and try again.
This one genuinely goes both ways, so the first job is telling which you are looking at.
Roblox's explanation: the client tries to establish a connection to the Roblox servers but times out due to a connectivity issue, low bandwidth or internet speed. The engine name is DisconnectTimeout.
The bandwidth part is worth taking seriously. Roblox's own guidance puts the floor at roughly four to eight megabits per second for a stable session. A connection that streams video fine can still sit below what a live game session needs for consistency, because the issue is packet loss and jitter rather than raw speed.
If other online games and services are also struggling, it is your connection. If only Roblox times out while everything else is fine, check the live status above — this code rises during platform trouble. If one person in the house triggers it by streaming, you have found your cause.
Operator documentation: en.help.roblox.com. One thing to know about Roblox's own articles for this family of codes. We compared them and the sections after “select your operating system” are byte-for-byte identical across codes 264, 266, 268, 277, 279 and 280 — the same reinstall, clear AppData and call your ISP sequence. Only a one-to-three line paragraph differs. So the official answer is close to the same for six unrelated problems, which is why the causes below matter more than the steps.
