How to Fix Call of Duty Connection Interrupted Errors

If you see the "connection interrupted" message in Call of Duty (COD), don‘t panic. This common error simply means there is a disruption in communication between your game and the COD servers. The good news is there are several ways to resolve connection interrupted problems on your own.

Step 1: Check Call of Duty Server Status

Before troubleshooting your setup, verify COD servers are actually up and running. According to Downdetector, over the last 90 days players reported connection issues with COD servers:

Outages spike during new game launches as millions of excited players try logging on at once. So before getting too deep in troubleshooting, visit the Activision Server Status page to see if COD services are down.

If servers are up, the problem likely lies on your end. Let‘s walk through some common causes and fixes.

Step 2: Update Your Game, Operating System, and Hardware Drivers

One of the easiest connection interrupted fixes is making sure your game, OS, and hardware drivers are 100% up-to-date:

• Game Updates: Close COD and reopen to download patches. Poorly optimized games are prone to connectivity issues.
• OS Updates: Install the latest Windows, Console OS, or mobile device updates. These often contain networking improvements.
• Graphic Card Drivers: Updated GPU drivers optimize performance and compatibility.
• Network Adapters: Outdated network adapter drivers can severely impact connectivity.

I recommend using automatic driver update utilities like DriverEasy to scan for outdated drivers and handle installations. This simplifies updating the various hardware components interacting with COD.

Step 3: Switch Your DNS Server

Your DNS server translates domain names (e.g. callofduty.com) to machine-readable IP addresses. It‘s an essential intermediary facilitating communication between your computer and game servers.

Sometimes DNS server congestion or incompatibility causes connection issues. I‘d recommend temporarily switching from your default ISP DNS server to Google‘s free DNS servers:

Google DNS IP Addresses

• 8.8.8.8
• 8.8.4.4

Follow these instructions to change DNS settings based on your operating system. Then test if COD connectivity improves.

If problems persist, try switching to OpenDNS or Cloudflare as alternatives. DNS flexibility varies by ISP and region though.

Step 4: Forward Ports for Your Platform

If DNS tweaking doesn‘t help, consider forwarding ports on your router. This opens inbound connections to your console, PC, or mobile device.

Recommended COD Ports

Follow this port forwarding guide with step-by-step instructions for configuring your specific router model.

Warning: Port forwarding improves connectivity but does lower your network security. Make sure to revert changes if problems persist.

Step 5: Test Your Bandwidth and Latency

COD‘s high pace gameplay requires low latency and decent bandwidth to avoid interruptions and lag.

I recommend running multiple speed tests over a week across different times of day. Pay attention to latency (ping) and packet loss percentages as well as bandwidth. Any pings over 100ms, packet loss over 5%, or speeds under 10 Mbps down could cause connectivity problems.

If your network struggles to meet these benchmarks, try the following:

• Test wired Ethernet versus Wi-Fi results
• Change Wi-Fi bands between 2.4Ghz and 5Ghz
• Upgrade internet plan or switch providers
• Relocate modem and router for better signal distribution

Of course there are always factors out of your control like network congestion during peak hours. But optimizing conditions where possible makes a difference.

Step 6: Reset Networking Equipment

As a last resort if COD keeps disconnecting, reset all networking equipment:

• Restart modem and router – Unplug, wait 30 seconds, plug back in
• Reset router – Factory reset and reconfigure from scratch
• Reset network adapters – Clear TCP/IP stack and winsock data
• IP flush DNS – Clear out bad DNS data in cache

Resetting often fixes lingering software and performance issues. Just make sure to backup settings before factory resetting devices.

Still Having Trouble? Contact Activision Support

If problems continue even after exhausting troubleshooting steps, reach out to Activision support. Provide traceroutes and ping logs documenting connection interrupted errors.

Activision can investigate server logs on their end and identify any account, compatibility, or network issues ruining game performance.

Stay calm and take methodical steps to solve Call of Duty connection interrupted errors. Small home network tweaks make a big difference. Let me know if the guide helps or if any questions come up! Happy gaming!
