Random game error.

One of the common reasons for many game connection problems is due to errors that game developers have not anticipated. These types of errors are not usually universal and may be triggered by some unique circumstances in some PC software environment.

In my experience, COD Black Ops Cold War runs smoothly although it took some time to join a lobby.

If Black Ops Cold War keeps disconnecting or showing an error without a clear pattern, it may be caused by a random bug.

Server issues.

For others, the main reason for connection issues is something outside a player’s control. Server issues are usually the primary cause for most connection problems in Call Of Duty franchises. At this time, many players are reporting challenges in connecting to the server most probably due to server inability to cater to connection requests.

Local network issues.

If there is no on-going server issues, the second most common reason why you may be having a hard time connecting to Black Ops Cold War multiplayer may be your own home network. You must ensure that your internet connection works and that it is not slow or intermittent.

Even if your connection at home works, it’s still possible that it may be cutting off, losing bandwidth, or becoming too slow at times. Any of these things can cause connection problems to the server when playing online.
