Server issues.

The most common reason for “cannot connect to online services” error is something that many players cannot control as it’s server-related. Activision games like the Call Of Duty franchise are known for server issues so the first thing that you need to check is the status of the game server. 

Server issues can occur randomly due to technical problems but also because of planned maintenance. At times, Activision may schedule maintenance days or weeks ahead.

How to fix Black Ops Cold War “Cannot Connect to Online Services” error

There are several solutions that you can try if you want to play an online on Black Ops Cold War but it keeps showing the “cannot connect to online services” error. Let’s discuss each of them briefly below.

Check the game server status.

The first important step that you must take is to verify if there are server problems. Game servers may sometimes go down due to unexpected glitches. For new and popular games such as Black Ops Cold War, too many players trying to play online may put enough pressure to the server and may result to temporary downtimes. 

Black Ops Cold War server update

At other times, Activision may intentionally force servers down to improve things, or to fix known bugs. To check, you can visit the official Activision website:

Once you’re in the site, make sure that you check the status indicator for your platform. If it’s not green, or if there’s an alert or message, there may be on-going connection error.

Power cycle the router.

If there are no declared server issues at the moment, your next troubleshooting step is to see if the problem is caused by an unresponsive router. Network equipment like routers, modems, switches, or hubs can lead to connection problems if they freeze or stops responding. 

To see if that’s the case, turn your modem or router off, unplug it from the power source, and wait for 30 seconds before turning it back on. 

Routers need to be refreshed from time to time, just like your computer or console so be sure to reboot it at least once a week, even if you are not experiencing any issues.

Run a speed test.

If you are still having the problem after the modem or router has been rebooted, the next good thing that you can do is to confirm if your PC or console suffers from slow connection issue. 

If you’re on PC, just pull up your favorite web browser and visit a site like to check your internet speed.

If you play Black Ops Cold War on a PlayStation (PS4/PS5) or Xbox (Xbox One or Xbox Series X/S), just go to the Network settings and run the built-in network speed test option.

If your download and upload speed goes down below 3Mbps, you may experience network lag and the game may be having a hard time maintaining connection to the servers.

If you are paying for a fast internet connection but the speed test result is way below the subscribed download and upload speeds, it can be due to low bandwidth. To check, try to disconnect any device that’s using your internet connection (wired and wireless), then run a speed test again. 

Keep in mind that multiple devices using your connection (such as streaming, downloading, or playing online games) can severely degrade the online experience on your PC or console.

Get help from your ISP.

If you are not sure how to troubleshoot your slow home network, or if you are experiencing a hard to fix problem like intermittent connection, the best thing that you can do is to contact your Internet Service Provider. 

Repair game files.

If you continue to have the same error after you’ve checked potential network issues, the last thing that you can try is see if repairing or reinstalling the game helps. 

If you play Black Ops Cold War on PC, you can attempt to repair the game files by doing the following steps:
