Check Call Of Duty Server Status

The first thing you should do when encountering this error is to check if the Call Of Duty servers are actually up and running. Server outages are a common cause of connectivity issues.

Check Call Of Duty Server Status

To check the server status:

  • Select Call of Duty: Call Of Duty from the game dropdown menu
  • Check the server status for your platform (PC, PlayStation, Xbox) under the Server Status section

If the servers show as offline or degraded performance, there’s nothing much you can do except wait for Activision to get them back up.

However, if the servers are online and you still can’t connect, move on to the next solutions below.

Restart Your Devices

Before troubleshooting your network settings or game files, try restarting your gaming device and router:

Restart Your PC

  • Press Windows key + R to open the Run dialog box
  • Type “shutdown /r /t 0” and press Enter to restart your PC immediately

Restart Your Game Console

  • For PlayStation: Press and hold the power button on your PS4/PS5 until it completely shuts down. Then disconnect the power cable for 30 seconds before reconnecting it and turning it back on.
  • For Xbox: Press and hold the Xbox button on your console for 10 seconds until it shuts down. Unplug the power cable and wait 30 seconds. Then plug it back in and turn on your Xbox.
Restart Your Router

Restart Your Router

  • Reconnect the power cable to turn your router back on

Restarting these devices often resolves temporary glitches, bugs, and connectivity issues. Now try launching Call Of Duty again to see if the error persists.

Disable Background Apps and Processes

Background applications and processes running on your PC or console can sometimes interfere with your internet connection. Close any non-essential apps before launching Call Of Duty:


  • Press Ctrl + Shift + Esc to open Task Manager
  • Go to the Processes tab
  • Right click on any non-essential background apps and select End task
  • Apps like web browsers, Skype, Discord etc should be closed

  • Go to My games & apps > See all > Games
  • Select non-essential apps and choose Quit

Now try connecting to Call Of Duty without these apps running in the background.

Connect Using a Wired Connection

If you are playing Call Of Duty over WiFi, try using a wired ethernet connection instead for more stable connectivity:

Connect Using a Wired Connection
  • Connect your PC or console to your router via an ethernet cable
  • Go to your network settings and make sure Wired/Ethernet is enabled
  • Disable WiFi so internet traffic goes through the wired connection

A wired connection eliminates issues like weak signal, interference and bandwidth congestion.

Troubleshoot Your Network Connection

Run the Network troubleshooter on Windows to diagnose and fix any network issues:

  • Type “troubleshooting” in the Windows search box and select Troubleshooting
  • Click on Additional Troubleshooters
  • Run the Internet Connections troubleshooter
  • Follow the on-screen instructions to complete troubleshooting

This scans your network components like WiFi, ethernet, DNS etc to identify and resolve problems.

Flush Your DNS Cache

A corrupted DNS cache can prevent connectivity to the game servers. Flushing it clears out this cached data:

On Windows

  • Press Windows key + R to open the Run command
  • Type “cmd” and press Ctrl + Shift + Enter to open the command prompt as admin
  • Type the following commands and press Enter after each one:
ipconfig /flushdns
ipconfig /registerdns 
ipconfig /release
ipconfig /renew
netsh int ip reset
netsh winsock reset

On Mac

  • Go to Finder > Applications > Utilities and open Terminal
  • Type the following commands and press Return after each one:
sudo killall -HUP mDNSResponder
sudo dscacheutil -flushcache 
sudo killall -HUP mDNSResponder

This will flush your DNS cache and register the DNS entries again.

Change Your DNS Server

Using custom DNS servers like Google or Cloudflare often resolves connectivity issues:

On Windows

  • Go to Control Panel > Network and Internet > Network and Sharing Center
  • Click Change adapter settings
  • Right click your active network and select Properties
  • Double click Internet Protocol Version 4 (TCP/IPv4)
  • Select Use the following DNS server addresses
  • Enter and and click OK

On Mac

  • Click the Apple icon and go to System Preferences > Network
  • Select your wired connection and click Advanced
  • Go to the DNS tab and click the + icon
  • Enter and and click OK

On Consoles

  • On PS4, go to Settings > Network > Set Up Internet Connection. Select Custom > Manual setup and enter as your primary DNS and as secondary.
  • On Xbox One, go to Settings > Network > Advanced settings. Select DNS settings and enter as your primary DNS and as secondary.

This will switch your DNS servers to Google’s public DNS which is often faster and more reliable.

Forward Ports for Call Of Duty

If you have access to your router’s settings, forwarding the correct ports can help establish a stable connection to Call Of Duty.

  • Sign in to your router’s admin page (
  • Go to Port Forwarding/Virtual Servers settings
  • Create new rules to forward the following ports:


  • TCP Ports: 3074, 27014-27050
  • UDP Ports: 3074, 3478, 4379-4380, 27000-27031, 27036

Refer to your router manual for exact steps. Once configured, save settings and restart your router.

Switch to Public Matches

Some ISPs block certain types of connections used by Call Of Duty. Switching to Public Matches instead of Private may avoid this:

  • Launch Call Of Duty and access Multiplayer
  • Press R1/RB to open Social menu
  • Select Triangle/Y to edit Match Settings
  • Change Matchmaking to Public instead of Private
  • Try finding a match now
