Troubleshooting: Disconnecting / Unstable Co-op

Fix frequent disconnects, lag, or session errors in REANIMAL Co-op.

Common Causes

  • Strict NAT: One or both players have restrictive router settings.
  • Server Load: Launch day issues or regional outages.
  • Driver / Game Version Mismatch: Both players must be on the same version.

Quick Fixes

  1. Direct Connection: Use wired Ethernet if possible.
  2. Restart Game: Close REANIMAL completely and re-launch.
  3. Check NAT:
    • Open: Best for hosting.
    • Moderate: OK for joining.
    • Strict: Can only play with Open NAT hosts.

Advanced Steps (PC)

Port Forwarding

If NAT is Strict, forward these ports (standard for PC multiplayer):

  • TCP: 80, 443, 3478-3480
  • UDP: 3478-3479, 3658, 50000-65535

Disable VPN

VPNs often interfere with P2P connections or region locking.
