Part 1: Disconnected Invalid Authentication R.E.P.O.

What It Means

This error typically appears when there is a mismatch between your login credentials and the R.E.P.O. server. It's often caused by token expiration, corrupted session files, or third-party authentication failures (like Steam login hiccups).

How to Fix

• Restart R.E.P.O. and Steam: Fully close both R.E.P.O. and Steam. Restart them to refresh any expired login tokens or cached credentials.
• Logout and Re-login to Steam: Log out of Steam completely and sign back in. This can revalidate your identity with R.E.P.O.'s servers.
• Run the Game as Administrator: Right-click on the R.E.P.O. shortcut and click "Run as Administrator" to ensure it has all necessary system permissions.

Part 2: R.E.P.O. Disconnected Client Timeout

What It Means

A client timeout means that your game took too long to communicate with the R.E.P.O. servers. It's a classic sign of internet instability or overloaded system resources.

How to Fix

• Check Your Internet Connection: Run a speed test and look for high latency or packet loss. Switch to a wired connection if possible.
• Lower In-Game Settings: Go to R.E.P.O.'s settings and reduce your graphics and network sync rates. Fewer resources mean fewer delays.
• Close Background Applications: Apps like Discord, Chrome, or file-sharing programs can hog bandwidth. Close them to prioritize R.E.P.O..
• Flush DNS Cache: Open Command Prompt (admin) and run ipconfig /flushdns to resolve network-related issues.
• Use a Game Optimizer like LagoFast: LagoFast helps reduce ping and packet loss by rerouting game data through optimized pathways. It can prevent timeout errors in real time.

Part 3: R.E.P.O. Host Disconnected

What It Means

This error occurs when the game host, whether player or server, drops out unexpectedly. It may be due to host-side crashes or internet instability.

How to Fix

• Check Server or Host Status: If you're not the host, confirm if the host's game crashed or their internet failed.
• Rejoin the Game: R.E.P.O. sometimes allows rejoining sessions. Quickly try to reconnect to salvage your run.
• Change Server Region: In R.E.P.O.'s settings or launcher, switch to a closer or more stable server region.
• Avoid Hosting on Weak Connections: If you're frequently the host, make sure you have strong upload bandwidth and no ongoing downloads.

Part 4: R.E.P.O. Error Disconnected

What It Means

This generic disconnection message doesn't offer much detail but often points to either network instability or a sudden software crash.

How to Fix

• Update R.E.P.O. to the Latest Patch: Developers often push hotfixes. Make sure your game is fully updated via Steam.
• Scan for Malware: Malicious software can interfere with network ports. Run a full scan using Windows Defender or Malwarebytes.
• Reinstall R.E.P.O.: A clean reinstall can resolve underlying file corruption causing the error.
• Reset Network Settings: Use netsh winsock reset and netsh int ip reset in Command Prompt to restore network configuration.
• Use Windows Event Viewer: Check Windows logs to find the exact cause if it's software-related, like memory access errors.

Part 5: R.E.P.O. Disconnected Maxccureached

What It Means

This error means your system has reached the maximum concurrent connection limit with the R.E.P.O. servers. It can happen due to background applications or too many rapid reconnects.

How to Fix

• Restart Your PC and Router: This clears any stuck or excessive network connections.
• Wait 5-10 Minutes Before Reconnecting: The R.E.P.O. server may temporarily block you if you reconnect too quickly after multiple failed attempts.
• Close Background Connections: Turn off game overlays, network monitors, or any background apps that constantly ping servers.
• Contact R.E.P.O. Support: If the problem persists, it may be account-related. File a support ticket with logs and error details.
• Limit Auto-Reconnection Tools: Avoid using any auto-reconnect features that might flood the server with requests.

Part 6: Disconnected Cause Server Timeout R.E.P.O.

What It Means

Server timeout suggests a failure in R.E.P.O.'s backend or an unstable connection from your system to the R.E.P.O. server.

How to Fix

• Check R.E.P.O. Server Status: Visit R.E.P.O.'s community pages or social media to see if servers are undergoing maintenance.
• Temporarily Disable Firewall: Your firewall may be blocking outbound connections to the server. Try disabling it and reconnecting.
• Switch DNS Servers: Change to Google DNS (8.8.8.8 / 8.8.4.4) or Cloudflare DNS (1.1.1.1) for faster resolution.
• Use LagoFast Game Booster: LagoFast routes your connection through stable servers, drastically reducing timeout issues.

Part 7: R.E.P.O. Disconnected Custom Authentication Failed

What It Means

This message is tied to custom login systems, which R.E.P.O. might implement in the future or during beta testing. It can mean your login credentials aren't recognized by the custom auth handler.

How to Fix

• Check for Experimental Login Features: If you've opted into beta features, try switching to the stable version on Steam.
• Clear Saved Credentials: Remove stored login tokens from your system. These may be outdated or mismatched.
• Re-enter Login Info: Log out completely and enter your credentials manually again, avoiding auto-fill.
• Temporarily Disable Antivirus: Overzealous antivirus software can interfere with token exchanges. Disable it briefly.
• Reset Account Password: If the problem persists, reset your account password and try logging in again.

Part 8: Disconnected Cause Exception

What It Means

This usually happens when the game hits a coding bug or software conflict that causes a runtime exception, leading to a forced disconnect.

How to Fix

• View R.E.P.O.'s Crash Logs: Navigate to the R.E.P.O. install folder and open the crash logs. Identify the specific exception thrown.
• Update Graphics Drivers: GPU-related exceptions can trigger sudden crashes, so you need to update via NVIDIA or AMD's official software.
• Increase Virtual Memory: Go to System Settings and select Advanced, then click Virtual Memory and allocate more to avoid memory-related exceptions.
• R.E.P.O.rt the Bug: If it's a consistent crash, R.E.P.O.rt it to R.E.P.O.'s support or forums with your log files.
