Updated November 6, 2026

Roblox Error 266 — “Your connection timed out. Check your internet connection and try again.” — appears when the Roblox client cannot establish a timely connection to Roblox servers due to connectivity issues (low bandwidth or slow internet speed). Roblox’s rule: “This error appears when the client application tries to establish a connection between the Roblox servers but are timed out due to connectivity issue (Low bandwidth or internet speed), this error appears on PC, Macs, and Mobile Devices.” This guide walks through the per-platform fixes Roblox recommends.

Why Error 266 happens

Roblox’s root cause: a connectivity issue that prevents the Roblox client from completing its connection handshake with Roblox servers within the expected time window. Specifically:

• Low bandwidth. Not enough data throughput for the Roblox connection to establish.
• Slow internet speed. Even if bandwidth is available, slow response times cause timeouts.
• Corrupted app data. Stale cache can disrupt the connection flow.
• Outdated app version. An old Roblox install may not handle current server protocols.

Error 266 appears on PCs, Macs, and mobile devices. Fixes converge on three themes: fresh install, cleared cache, and different network.

Quick network test

Four ways to verify your network before contacting support:

• Speed test: fast.com or speedtest.net — Roblox needs ~5 Mbps minimum.
• Ping test to Roblox servers: cmd prompt → ping roblox.com — <150ms acceptable.
• Different connection: mobile hotspot or neighbor’s Wi-Fi — rules out your router.
• Restart router: power off 30 seconds, power on — resolves many connection issues.

When to contact Roblox Support

If all per-platform fixes and network tests fail, submit a support ticket with:

• Roblox Username.
• Device model + OS version.
• Exact error message text.
• Speed test and ping test results.
• Steps you’ve tried.

Roblox Support response: 1-3 business days typically. For urgent issues, their social-channel presence (Twitter/X @Roblox) sometimes flags priority cases.

FAQ

What causes Roblox Error 266?

Roblox’s explanation: a connection timeout due to connectivity issue — low bandwidth or slow internet speed. The client can’t complete its handshake with Roblox servers within the expected time window.

Is Error 266 the same as being banned?

No. 266 is a connection timeout, not a ban. Players can rejoin once the network issue is resolved.

What fixes Error 266 on Windows?

Uninstall Roblox (Settings → Apps), clear app data (CMD: rmdir /s %LocalAppData%Roblox), restart PC, reinstall, then verify network (speed test + ping).

What minimum internet speed does Roblox need?

Roblox doesn’t publish an exact minimum, but ~5 Mbps download typically suffices for most experiences. Lag-sensitive games (competitive, high-player-count) benefit from 10+ Mbps.

Does changing Wi-Fi fix Error 266?

Yes, often. Roblox’s own recommendation: “Try connecting your system to a different source of internet connection and see if the issue persists.” A mobile hotspot or different Wi-Fi rules out router-side issues.

Why does Error 266 show date/time as a fix?

Incorrect device date/time causes SSL certificate errors that look like network timeouts. Roblox’s HTTPS handshake needs accurate time to validate server certificates.

What if Error 266 persists after all fixes?

Contact your ISP (Roblox’s rule: “it is recommended to connect with your internet connection provider for further troubleshooting”) AND submit a Roblox Support ticket with your device + speed test details.
