Sometimes, it happens if you have two routers (double NAT). This problem blocks connections, makes it harder to join games, and can cause higher lag or matchmaking errors. Now that you know the main causes, let’s review all the effective methods players have used to solve this problem:
1. Reset Your Firewall
As a first step, try resetting your Windows Firewall. This will restore Firewall settings to their original defaults and let you choose which apps are allowed through again.
2. Set a Static IP
Your next option is to set a Static IP address for your device. This can help avoid IP conflicts and improve your network reliability for online play. Many users have found this resolves their NAT problems.
3. Forward Ports
Another major reason for NAT issues is that your router might be blocking the specific ports that Call of Duty Warzone needs to communicate online. To solve this, you can manually forward the required ports through your router’s settings. Note: The exact steps to forward ports can vary depending on your router brand. If these instructions don’t match exactly, refer to your router’s manual or the manufacturer’s website for details.

4. Add the Game as an Exception in Firewall
If you’re still experiencing connection problems, try adding Call of Duty Warzone as an exception in the Windows Firewall. Sometimes the firewall blocks game traffic, which can cause NAT problems. Creating this exception tells Windows Firewall to always allow game connections.
