Specific antivirus software will detect and remove some game files as false positives. This problem is uncommon. Another issue consumers have mentioned is that using security software on their computers causes them problems.

Firewalls incorporated into some security software can prevent games from connecting to the internet. Conventional War could be the source of the problem if your antivirus software has disabled it.

To test if you can access the internet platforms, briefly disable any security software on your machine and then run Call of Duty: Modern Warzone.

Launch your VPN or antivirus programs and deactivate them for a few moments in the preferences. You can also use Task Manager to terminate programs.

You could do that by ctrl-clicking the taskbar and choosing “Task Manager.” Locate VPN or antivirus programs in the task manager, ctrl-click, and select “End Task.” End Task will close the program for you.

In this situation, you’ll have to reopen the programs manually. If you don’t reboot your pc, they’ll stay closed.

10. Confirm Firmware Updates For The Console

You must not have out-of-date software on your computer. The same is true with consoles. Ensure the console you’re using has the most recent firmware installed.

What exactly is firmware? You might wonder why you are being asked this question when you’re not a techie.

Firmware is similar to PC BIOS and is stored in the console’s memory system. An obsolete firmware version may prohibit the system from successfully connecting to Activision; while this seems unlikely, you should never rule it out.

Specialists also advise that you update the firmware and operating system of your digital equipment and devices as soon as a new software update is released.

11. Port Forwarding

The port forwarding technique was one of the ancient strategies players used to lower latency in an online game in the early 2010s when the web was becoming more accessible.

Nevertheless, this strategy became outdated when consumers accessed more dependable and quicker broadband internet.

Communication inquiries are forwarded from one port address and phone number to another using port forwarding. Remote workstations on the internet could potentially link to a desktop device or service inside a LAN arrangement.

Because of the structure of port forwarding, many players used it to lower their ping in multiplayer mode.

To utilize port forwarding, follow these steps:

Login to your Account on your computer and enter the Network address. Enter the credentials provided by your Internet service provider (ISP) or those you choose during router configuration.

Locate your port forwarding options after signing in. These parameters should be under advanced options. However, they may vary from network to network due to the varied numbers of ports.

If you notice terms like “NAT forwarding,” “NAT,” or “Port triggering,” don’t click on them. This is the configuration you require.

Now, for each system listed below, configure port forwarding:

PC

TCP: 3074,27014-27050

UDP: 3074,3478,4379-4380,27000-27031,27036

PS4

TCP: 1935,3478-3480

UDP: 3074,3478-3479

Xbox One

TCP: 3074

UDP: 88,500,3074-3075,3544,4500

If you’re confused about utilizing these ports, see your router’s manual or Google for complete instructions on using terminals with your specific router type.

12. Check The Activision Customer Support Page

If you can’t discover any Tweets regarding “server offline due to maintenance” after reviewing the server status webpage, consider contacting the Activision client service page for possible repairs.

The Activision customer service page will first assist you in identifying your issue, then direct you to a particular page with a cure to your problem. The issue in our instance is a server connectivity issue.

  • On the site, this is how to find your problem:
  • Go to Activision’s leading customer service website here:
Go to Activision's leading customer service website
  • Choose “Call of Duty: Modern Waronze” |Choose your game” in the “Game section.

This is yet another way of identifying the fundamental problem, similar to the server state. The official Twitter account for Call of Duty publishes information about the games, including server statuses.

If you use Twitter, you can stay up to date by following the official Call of Duty account.

If the systems are offline for maintenance, the Twitter account will give an update to inform users ahead of time, and It will notify you that you will be unable to play for some time.

Check Call of Duty Official Twitter

You’ll save time and have more time to accomplish other things. 

The servers do go down for maintenance now and then, but not for extended periods. There’s a good chance you’ll never hear anything about servers being down for care.

If you’re having trouble with Modern Warfare 2’s unable to access internet services error, consider checking Twitter first before attempting any workarounds.

It is might possible that the server is down for service.

14. Change the Region

To resolve the Call of Duty Modern Warfare Unable To Access Online Services problem, we recommend changing the location while downloading or building up a game. The game automatically identifies the site. You could adjust it according to your needs.

  • Go to the Blizard Launcher website.
  • Then go to the Battle Net menu in Blizzard.
Change the Region
  • Choose Call of Duty: Modern Warfare from the drop-down menu.

  • Click on it and select anyone from the following: THE UNITED STATES OF AMERICA, EUROPE, OR ASIA
  • Select a region other than your present one.
  • When you’re finished, try running the game.

15. Try Another game & Restart your Network Connection.

Modern Warfare refuses to let anyone play the game in peace once you’ve exhausted all of your alternatives. Try a different console game if you have one.

It eliminates the chance that the problem is not with Call of Duty but with internet access.

If you can play other games, it’s clear that the problem isn’t with your connection. The Call of Duty servers isn’t working correctly. If that doesn’t work, reboot your internet connection.

After resuming your connection, try out some other games. If you still can’t play any games after rebooting, contact your ISP and request them to fix the problem.

16. Try Re-login Later

Despite your best attempts, you can still not connect to the Call of Duty: Modern Warfare servers. Re-enter your password at a later time.

The servers may appear to be up on the server status site, but owing to technical difficulties, a contact between Call of Duty and the servers may be impossible to ascertain.

Such problems are difficult to spot, and you may not even be aware of them. In these situations, there is little you can do but wait for the problem to be fixed.

If you’re having trouble connecting your game to the network, try logging in again at a later time.

17. Permit Call of Duty Black Ops Cold War via Windows Firewall

In several situations, your firewall may block the link between the server and the game launchers. In this scenario, you can try to solve the issue by permitting the game through Windows Firewall.

Furthermore, your domineering antivirus package could be the root of the problem. As a result, you should add the game and its launcher (Battle.net) to your antivirus’s exceptions or exclusions list.

To permit the videogame to run via Windows Firewall, follow these steps:

  • To start, hit Windows + R to open the Run dialogue box.
  • To launch the Windows Defender Firewall panel, put firewall.cpl into the command prompt and hit Enter.
put firewall.cpl into the command prompt and hit ok
  • Then, on the upper left bar, choose to Permit an application or function via Windows Defender Firewall.
choose the Permit an application or function via Windows Defender Firewall.
  • After that, click the Change gear icon; therefore, choose the Permit another application button.
  • Then, to add Battle.net’s runtime and BlackOpsColdWar.exe files to the Allowed programs and services table, start browsing and choosing them.
  • Ensure the additional apps are enabled, then activate the Hidden and Open checkboxes.
activate the Hidden and Open checkboxes
  • Lastly, tap the OK button to save your modifications.

You can consider restarting the game and seeing whether you can access internet platforms this time. If the problem remains, move on to the next possible solution to resolve the mistake.
