Destiny 2: Network Error 'Cabbage' and 'Centipede' - Repair Diagnosis

⚠️ SAFETY WARNING. Incorrect intervention on network devices or improper modification of router settings can compromise the security of your home network or cause total disconnections. It is recommended to proceed with caution. ReeFix provides this diagnosis EXCLUSIVELY for educational and informational purposes.

HIGH PRIORITY

'Cabbage' Error Analysis (Firewall/IDS Block) — Probability: 53%

• Technical Logic: Destiny 2 uses a hybrid network architecture that requires a constant exchange of Peer-to-Peer (P2P) UDP packets between players. Commercial routers (especially those provided by ISPs branded Technicolor, Thomson, or Alcatel) interpret this massive traffic as a UDP Flood cyber attack, activating internal security filters and blocking the connection.
• Experience Signal: This issue almost always manifests at the exact moment you attempt to access a social area (such as the Tower) or at the launch of a group activity.
• Quick Checks:
  1. Access your router's control panel via browser.
  2. Locate the Firewall section and temporarily disable the "IP Flood Detection" or "SPI Firewall" option.
  3. Enable the UPnP service status to allow dynamic port opening.
  4. Control Test: Temporarily place the console's IP address in the router's DMZ (Demilitarized Zone). If the error disappears, the cause is 100% confirmed to be the router's firewall.

| Error | Main Cause | Typical Symptom | Key Solution | | :--- | :--- | :--- | :--- | | Cabbage | Router Firewall / IP Flood Detection block | Immediate disconnection when accessing social areas (Tower) | Disable "IP Flood Detection" / "SPI Firewall" and enable UPnP | | Centipede | Strict NAT (Type 3) or ISP CGNAT presence | Inability to connect to Bungie authentication servers | Configure Port Forwarding (Port 3074) or request a dynamic public IP |

MEDIUM PRIORITY

'Centipede' Error Analysis (Strict NAT or CGNAT) — Probability: 31%

• Technical Logic: The Centipede error indicates the client's inability to establish a stable connection with Bungie authentication servers. It often depends on a Type 3 (Strict) NAT or the operator's use of a CGNAT (Carrier-Grade NAT) system, which shares the same public IP among multiple users, preventing correct port routing.
• Verification and Resolution:
  • Check the NAT status in your console's network settings.
  • If the NAT is restricted, configure a static IP on the console (DHCP Reservation) and set up Port Forwarding on the router for the following ports:
    • TCP: 3074
    • UDP: 3074, 3097-3099
  • If the problem persists even with open ports, contact your ISP and explicitly request the deactivation of CGNAT and the assignment of a "dynamic public IP".

LOW PRIORITY

Transmission Medium Instability and ISP Routing — Probability: 16%

• Technical Logic: Micro-interruptions in the Wi-Fi signal cause packet loss that the game engine cannot compensate for, generating sudden disconnections.
• Hardware Solution: Replace the wireless connection with structured cabling. If the operator's hardware is obsolete or has a saturated CPU, the most efficient solution is to put the operator's modem into "Bridge" mode and connect a dedicated third-party router.

Recommended components for hardware resolution:

• Ugreen Cat 7 Ethernet Cable (Eliminates Wi-Fi packet loss)
• TP-Link TL-SG105 Gigabit Ethernet Switch (Relieves the distribution load of the wired network)
• ASUS RT-AX53U Wi-Fi 6 Router (Optimal management of UPnP and NAT tables for gaming)

🩺 Economic Evaluation Report

• Intervention Difficulty: ⭐⭐ Medium (Requires access to router settings).
• Software / DIY Cost: €0 (Resolvable by configuring the existing router).
• Hardware Cost (Optional): €40–€80 for a third-party router if the ISP modem is locked or unstable.
• Technical Labor Cost: €30–€60 for a home network technician intervention.

📋 Report for the Network Technician (Handoff)

"The Destiny 2 client exhibits systematic disconnections with Cabbage and Centipede errors. The problem is traceable to the saturation of the router's SPI filter table and the failed negotiation of UDP ports in P2P mode. It is requested to disable anti-flood/IDS filters on the router, configure a static IP for the console with dedicated Port Forwarding (UDP Port 3074 and range 3097-3099), and verify that the ISP's WAN address is not behind CGNAT."

If the DMZ test resolves the error, configure UPnP and Port Forwarding or replace the hardware with an ASUS RT-AX53U Wi-Fi 6 Router; otherwise, contact the ISP to request CGNAT deactivation.

If you experience sudden micro-disconnections on the Wi-Fi band, it is recommended to access the wireless settings and manually set a static radio channel instead of leaving it in automatic mode, a step that stabilizes the signal and avoids annoying network crashes during gaming sessions.
