Fix Among Us Packet Error Guide

The ‘Reliable Packet 1 (size=15) was not ack’d after’ error in Among Us is a common frustration that kicks players out of matches with a disconnection message. This network-related issue often stems from server overload, regional mismatches, or local connectivity problems, affecting millions during peak playtimes. Whether you’re on PC, Android, iOS, or consoles, this guide provides original, tested solutions to restore smooth multiplayer sessions.

Understanding the Reliable Packet Error

This error indicates that the game’s initial connection packet—essential for handshaking with Among Us servers—fails to receive acknowledgment within a timeout period, typically after several milliseconds and resend attempts. Unlike general lag, it points to a failure in reliable data transmission, where UDP packets (used by Among Us for low-latency gameplay) get dropped or blocked.

• Packet Basics: Among Us relies on UDP for fast, real-time communication. ‘Reliable Packet 1’ is the first critical message confirming your presence to the host or public lobby.
• Common Triggers: High server load, geographic distance to servers, firewalls, VPN interference, or unstable Wi-Fi.
• Impact: Immediate kicks from lobbies, preventing joins or hosts, disrupting public and private games alike.

Recognizing symptoms early—such as the error popping up right after selecting ‘Play Online’—allows quick intervention before full frustration sets in.

Quick Fixes: Start Here for Instant Relief

Most players resolve this error with simple, no-tech tweaks. Test these first before diving deeper.

1. Switch Server Regions: Click the globe icon in the bottom-right of the main menu. Cycle through North America, Europe, Asia, or others. Proximity reduces latency; e.g., US players often succeed by avoiding overloaded NA servers.
2. Wait and Retry: Servers under heavy load reject connections. Pause 5-10 minutes, check status via official Discord or Twitter, then attempt again.
3. Restart the Game: Fully close Among Us (via Task Manager on PC) and relaunch. Clears temporary glitches.

These steps succeed 70-80% of the time during non-peak hours, per community reports.

Network Optimization Techniques

If quick fixes fail, target your internet setup. Among Us demands stable, low-ping connections for packet reliability.

Step-by-Step Router Restart: Unplug your modem and router for 30 seconds, plug back in modem first, wait for lights to stabilize, then router. Reconnect devices and launch Among Us.

Ping Test (PC Only): Open Command Prompt, type ping amongus.innersloth.com -t. Ideal ping under 100ms; over 200ms signals issues. Switch regions if NA pings spike.

Platform-Specific Troubleshooting

PC (Steam/Epic Games)

Steam users report frequent issues during sales or updates.

• Verify game files: Steam Library > Among Us > Properties > Local Files > Verify Integrity.
• Epic Launcher: Close fully, delete %localappdata%\\AmongUs folder, relaunch.
• Update graphics drivers (NVIDIA/AMD) to prevent indirect network conflicts.

Mobile (Android/iOS)

Mobile hits this on cellular data, especially Sprint/T-Mobile.

• Force Wi-Fi only; disable mobile data for gaming.
• Clear app cache: Settings > Apps > Among Us > Storage > Clear Cache (not data, to preserve progress).
• Update app via Google Play/App Store; outdated versions mismatch servers.

Consoles (Switch/PS/Xbox)

Console errors tie to NAT type.

• Open NAT: Router settings > Port Forward UDP 22023 (game port).
• Test connection in console network settings; aim for Type 2 or better.

Advanced Solutions: Firewalls and Ports

Firewalls block ‘Reliable Packet 1’ as it’s the handshake.

Windows Firewall:

1. Search ‘Windows Defender Firewall’ > Allow an app > Add AmongUs.exe (usually in Steam\\steamapps\\common\\Among Us).
2. Advanced: New Inbound Rule > Port > UDP 22023 > Allow.

Antivirus Interference: Temporarily disable real-time protection (e.g., Avast, Norton). Add Among Us to exceptions if it recurs.

Router Port Forwarding: Log into router (192.168.1.1), UPnP enabled or manual forward UDP 22023 to your device’s local IP. Use ipconfig (PC) for IP.

Preventing Future Disconnects

Proactive habits minimize recurrence:

• Play Off-Peak: Avoid weekends/evenings in your timezone.
• Stable ISP: Fiber > Cable > DSL for gaming.
• Host Privately: Use Discord for codes; smaller lobbies strain less.
• Monitor Server Status: Follow @AmongUs or Innersloth status pages.

Custom mods like Town of Us exacerbate errors; stick to vanilla for stability.

When to Seek Further Help

If all fails:

• ISP Check: Run speedtest.net; under 10Mbps upload causes issues.
• Official Support: Submit ticket via Innersloth site with error logs.
• Community: Reddit r/AmongUs or Steam forums for region-specific advice.
