Tools You'll Need

How to Fix Error Code ChewedNova

  1. Check Halo Infinite Server Status

  2. Restart Halo Infinite Completely

  3. Restart Your Router and Modem

  4. Check and Improve Your NAT Type

    Only place one device in your router's DMZ at a time. DMZ exposes that device to the open internet, so ensure your console or PC has its own firewall enabled.

  5. Switch to a Wired Ethernet Connection

  6. Change Your DNS Servers

  7. Flush DNS Cache and Reset Network Stack (PC Only)

    Running 'netsh winsock reset' will require a restart and may temporarily affect other network applications. Save any open work before proceeding.

  8. Verify Game Files or Reinstall (PC Only)

    Reinstalling Halo Infinite will require re-downloading up to 60+ GB of data. Ensure you have enough disk space and a stable internet connection before starting.

  9. Check for Windows or Console System Updates

  10. Temporarily Disable VPN or Firewall

    Do not leave your firewall disabled permanently. Re-enable it after testing and add a specific exception for Halo Infinite instead.

When to Call a Professional

If you have tried every step above and ChewedNova persists only for you (not a server-wide outage), contact your Internet Service Provider (ISP). Ask them to check for packet loss, line instability, or CGNAT (Carrier-Grade NAT) on your account — CGNAT in particular locks your NAT type to Strict and cannot be resolved without ISP intervention. You can also contact Halo Support at https://aka.ms/HaloSupport and submit a ticket with your error details, gamertag, and region. If the issue is account-specific, support agents may be able to resolve it server-side.

Frequently Asked Questions

What does ChewedNova mean in Halo Infinite?
ChewedNova is an error code that appears in Halo Infinite when your game loses its connection to 343 Industries' multiplayer servers. It can occur mid-match or when trying to join one, and is usually caused by network instability, a strict NAT type, a server outage, or corrupted local network settings.
Is ChewedNova a server-side problem or my fault?
It can be either. If many players are reporting ChewedNova at the same time, it is almost certainly a server outage on 343 Industries' end and you just need to wait. If only you are getting it, the issue is likely on your network — your router, NAT type, DNS, or internet connection.
How do I fix ChewedNova on Xbox?
On Xbox, start by restarting your console and router. Then check your NAT type under Settings > General > Network Settings — it should say 'Open.' If it says 'Strict' or 'Moderate,' enable UPnP on your router or forward the required ports. You can also change your DNS to 8.8.8.8 and 8.8.4.4 under Advanced Network Settings on the Xbox.
Why do I keep getting disconnected from Halo Infinite multiplayer?
Repeated disconnections in Halo Infinite are usually caused by a weak or unstable Wi-Fi connection, a Strict NAT type blocking peer connections, packet loss on your internet line, or ongoing server issues. Try switching to a wired Ethernet connection, enabling UPnP on your router, and running a ping test to check for packet loss.
Will I lose my match progress or rank because of ChewedNova?
If ChewedNova kicks you from a ranked match, you may receive a matchmaking ban or a temporary CSR (rank) penalty, especially if the game detects it as an early quit. 343 Industries has stated that obvious server-side disconnections are generally not penalized, but if the disconnect appears to originate from your end, a short ban or rank penalty may apply. Fixing your connection stability is the best way to avoid this.
