How to fix Modern Warfare unable to access online services error

Call of Duty is an iconic game franchise that has surely reached the heights of popularity and success that no other FPS has ever achieved. The franchise set the bar even higher with 2019’s COD Modern Warfare. Built from the ground up, Modern Warfare offered improved gameplay and graphics, compared to its predecessors. The game still has a massive player base that enjoys playing it online solo or co-op.

However, as with any online multiplayer game, the game can run into errors and issues. One of the more common errors the players get on Modern Warfare is the “unable to access online services” error when they try to connect online.

This error also shows up in the latest and greatest battle royale game, Warzone, when the game client has connectivity issues. If you are getting the unable to access online services error in Call of Duty: Modern Warfare/Warzone, don’t worry. We have compiled a list of the most effective and reliable fixes for this issue.

Causes of “Unable to Access Online Services” in Modern Warfare

There are many reasons for this particular error. The Modern Warfare servers are packed as a huge number of players play the game regularly. If the servers are overloaded and exceed a certain player threshold, it will prevent more players from connecting online until the servers are back to normal. Sometimes, server maintenance or a bug can also be the issue. In this case, it’s best to wait and see if there’s a possibility of a new patch release.

Technical issues on Activision’s side can also disable online connectivity for a while. But that’s not all. It’s also entirely possible that there isn’t any issue with the servers and the problem is originating from the player’s side. This includes a slow or unstable internet connection, an outdated game version, or corrupted game files.
