How do you fix Roblox Error Code 771 (Teleport failed: Target server is full)?
Fix Roblox Error Code 771 quickly. Understand how server capacity race conditions happen during cross-server teleports and how to join alternative matchmaking instances.
How do you fix Roblox Error Code 771 (Teleport failed: Target server is full)? Roblox Error Code 771 occurs during cross-server teleports when the destination server reaches its maximum player capacity before your client connection completes handoff. This is a 100% server-side capacity race condition resolved by retrying matchmaking after 15 seconds to allow the matchmaker to allocate a fresh server instance.
| Telemetry Metric | Verified Value |
|---|---|
| Error Classification | Server Side Capacity & Matchmaking Race Condition |
| Trigger Event | Teleporting into populated raid or event servers |
| Hardware/Client Impact | None; local client files and network are undamaged |
| Best Workaround | Party leader re-initiating teleport with empty lobby |
| Average Resolution Time | 15 to 30 seconds |
Why Error Code 771 Occurs
Roblox Error Code 771 states: "Teleport failed: Target server is full or unavailable. (Error Code: 771)". Unlike client crashes, this message confirms your client communicated successfully with Roblox infrastructure, but the specific game server assigned to you hit its maximum player limit.
This frequently happens during high-stakes raid teleports in games like Blox Fruits, Deepwoken, and Anime Last Stand when dozens of players attempt to enter the same boss instance simultaneously.
Understanding Matchmaker Race Conditions
When an automated matchmaker reserves slots for players, multiple clients across different hubs can receive the same server IP simultaneously. If another player completes their connection handshake 50 milliseconds faster, the remaining slot fills, leaving your client with Error 771.
Recommended Solutions for Players and Parties
1. Wait 15 to 20 seconds before attempting to teleport again to ensure the matchmaker spins up a new instance.
2. If playing in a squad or party, have the party leader disband and re-invite party members in an empty lobby before queueing.
3. If joining a friend via profile, select a server from the game's "Servers" tab with at least 3 to 4 open slots rather than following them into a 19/20 full server.

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.
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.
