What are the reasons for Call Of Duty Black Ops Cold War Disconnected from Server error?

We’ve identified four common reasons why your Call Of Duty Black Ops Cold War game may not be connecting to the server, or keeps getting disconnected and showing the frustrating “disconnected from server” error. Let’s check each of the factors quickly.

Black Ops Cold War disconnected from server

Server outage or maintenance.

A huge number of players may experience disconnected from server error in the course of their Call Of Duty Black Ops Cold War gaming due to server downtimes. Massively popular games like the Call Of Duty games are being played by millions of people and from time to time, there can be planned and unplanned server outages. 

If your problem is due to a server issue, there’s nothing much that you can do but wait. 

Home network connection issues.

For others, the reason why they are unable to join a party with their friends or play online on Black Ops Cold War is something within their home network. One of the common problems that a lot of people encounter is slow internet connection. This can be due to their network equipment becoming unresponsive, ISP-related issues, or low bandwidth.

Some may also experience intermittent connection problems, especially if they are on wifi. 

Other applications interfering with the system.

For PC gamers, another possibility that they should consider, especially if their internet connection appears to be working normally and there’s no known server problems at the moment, is interference from third party software. 

Programs that run together with Call Of Duty Black Ops Cold War may impact the performance of the game, both offline and online. At other times, the game may lag and suffer from low framerates because another application is hogging resources. 

For some, presence of malware may significantly degrade the performance of their PC and even cause it to lose connection randomly. If your PC has a virus or malware that seem to manipulate the internet connection or cause the machine to briefly disconnect from the internet, your online gaming experience may become frustrating.

Corrupted game files.

A few people may encounter gaming issues if game files become corrupted. This can sometimes occur after a system update goes bad, or when a third party application or malware damaged your computer’s files. 

How to fix COD Black Ops Cold War “Disconnected From Server” error?

If you are experiencing connection problems when playing Call Of Duty Black Ops Cold Ware and you are getting the disconnected from server error, these are the things that you can do:

Fix #1: Keep everything updated.

First, you want to make sure that the game is running the latest client version. This is usually easy as you will be prevented from joining a match if the game is outdated. Simply update the game if you’re prompted to do it before doing any troubleshooting.

Fix #2: Verify servers are up and running.

Knowing if there is a server issue currently happening is an important troubleshooting step in this situation. 

Visit the official Activision server status page by following this link:

Black Ops Cold War server update

Alternatively, you can also go Xbox Live Status page or the PlayStation server status page for any issues related to their online services.

Fix #3: Restart game or device.

If the servers are working normally, the next good thing that you can do is to see if Black Ops Cold War has simply encountered a random game bug. To do that, simply close the game and relaunch it. 

If reloading the game won’t change anything and you still get the server disconnected error, try to reboot your PC, PS4, PS5, Xbox One, or Xbox Series X/S.

Fix #4: Troubleshoot your internet connection.

If you are still experiencing the disconnected from server error, you also need to check your internet connection. 

Power cycle the router.

To do that, the first thing that you can try is to turn off the router and unplug it from the power source for 30 seconds. This should allow the device to refresh and hopefully clear the clogged connection.


Check for slow connection.

If a router reboot will not fix the error, you would also want to know if it’s due to a slow internet connection on your PC or console. To do that, run a speed test. If you play on a PC, just pull up a web browser and check your network information by running

If you play COD Black Ops Cold War on an Xbox or PlayStation, you can run a speed test in your console’s network settings.

I’ve personally tried running Black Ops Cold War multiplayer on 5MBps download speed without any noticeable lag or degraded online experience. If your connection speed is slower than that though, it may potentially cause a problem.

If you suspect that your connection is slow, try disconnecting other devices from your network again. If there are multiple mobile phones, consoles, or PCs streaming Netflix or downloading huge files, that can cause low bandwidth issue when you’re playing an online game.

Fix #4: Use wired connection.

If you are on wifi, it’s possible that the reason for your problem is signal interference. Try connecting your PC or console directly to the router by a LAN cable and see if that will fix the problem.

Router ethernet

If a wired connection is not possible, try moving the console or computer nearer to the router.

Fix #5: Repair game files.

A few number of people may experience Black Ops Cold War disconnected from server due to corrupted files. If you are positive that there’s no existing server issue and your internet connection at home is not at fault, you may need to delete and reinstall Call Of Duty Black Ops Cold War.
