How do you fix Roblox Error Code 769 (Teleport failed: Client reconnect failed)?
Solve Roblox Error Code 769 during sub-place teleports. Learn why network handshakes drop between matchmaking instances and how to stabilize packet routing.
How do you fix Roblox Error Code 769 (Teleport failed: Client reconnect failed)? Roblox Error Code 769 indicates that your network client failed to establish a secondary handshake with the destination game instance during a TeleportService handoff. It is triggered by local DNS latency, packet loss spikes, or aggressive firewall filtering, and is resolved by flushing DNS and rejoining from the primary lobby.

Why Teleport Handshakes Drop
Roblox games frequently use TeleportService to move players between main hubs and dungeon instances (e.g. Dungeon Quest, Deepwoken, Blox Fruits). When you touch a portal, your client disconnects from the current server and opens a new connection to the destination instance.
If your ISP resolver takes longer than 5 seconds to resolve the new instance endpoint or drops UDP packets during authentication, Roblox displays: "Teleport failed: Client reconnect failed. (Error Code: 769)".
Fix 1: Flush DNS Resolver Cache
Stale DNS records often prevent your system from locating newly provisioned Roblox cloud servers:
1. On Windows, press Win + R, type cmd, and press Enter.
2. Execute the command: ipconfig /flushdns
3. On macOS, run: sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder
Fix 2: Configure Fast Public Anycast DNS
Default telecom DNS servers often introduce regional lookup latency. Switching your network adapter to Cloudflare DNS (1.1.1.1 and 1.0.0.1) reduces handshake lookup times from 80ms down to sub-10ms, eliminating Error 769 timeouts.
Fix 3: Avoid Rapid Portal Cycling
Stepping in and out of matchmaking portals rapidly queues conflicting teleport requests. Step out of the portal area, wait 10 seconds for prior matchmaking sessions to clear, and re-enter.

Error Code 279 indicates a network connection failure. Fix this by disabling your Windows firewall or antivirus temporarily, switching from Wi-Fi to an ethernet cable, restarting your router, or changing your DNS settings to Google DNS (8.8.8.8).
Roblox Error Code 516 occurs when the destination game instance reaches its maximum player capacity between the moment you initiate the connection and when the handshake completes. It is resolved by selecting a low-population server from the experience's Servers tab or generating a private VIP server.
