How to Troubleshoot error code 65536 in Call Of Duty (COD) Modern Warfare

Like many games that use the capabilities of the Internet, Call of Duty: Modern Warfare is not immune to random errors or connectivity problems. Sometimes servers go down, and these are the times when players may encounter error code 65536 in Call of Duty: Modern Warfare. What does this error code mean and what causes it? That’s why we’re here.

Simply put: Call of Duty: Modern Warfare error code 65536 corresponds to a connection problem between the user and the game’s servers. It’s caused by a server-side connection, basically a server failure, and doesn’t seem to be related to the user’s hardware or network configuration. In other words, the problem is out of the player’s control.

This is a bug that has occurred in the previous Call of Duty games, including Infinite Warfare, but has not been directly addressed by Activision support. As a result, there is still no official information on how to avoid the bug. It’s frustrating, isn’t it?

Power-cycle your router

Sometimes, simply rebooting your router is enough to correct a connection error. If your network devices have been in use for a long time, sometimes minor errors can occur.

To minimize the risk of network errors, you should reboot your router at least once a week by unplugging it for 30 seconds.

Checking the server status

To check if the servers are down, go to Activision’s official support page and check if the online service for your specific platform is marked with a green circle (as in the image below).

You can also follow Activision’s Twitter feed for updates. If the problem with the server continues, you will have to wait for it to be resolved.

Installing Updates

Whether you are experiencing problems or not, it is highly recommended that you keep your PC or console software update.

If you play Call of Duty Modern Warfare on your PC, be sure to install the following updates:

  • All games
  • All applications
  • Windows Operating System
  • Drivers.

If you’re playing on your PS4 or Xbox One, you’ve probably already updated the software. If not, you need to manually check for a software update that you still need to install. If necessary, restart the console by turning it off in the normal way and unplugging it from the power source for about 30 seconds.

Make sure that your Internet connection is not slow or intermittent

If your Internet connection is slow or dropped constantly, it may indicate that you are having problems with your ISP.

  • Restarting your home router is usually enough to troubleshoot your home network.
  • However, if your Internet connection is consistently slow or intermittent, the problem may be outside of your home.
  • Let your ISP know so they can help you solve the problem.
