How To Fix COD Warzone 2.0 Connection Failed Error | NEW in 2024

Are you getting the “connection failed” error when playing COD Warzone 2.0? In this guide, we’ll explain to you what this error is and the solutions that you can do to fix it.

What does Connection Failed error mean on Call Of Duty Warzone 2.0?

As the error name suggests, “connection failed” error is an indication that your PC, PS4, or Xbox One, is unable to go online and play Call Of Duty Warzone 2.0 as it cannot connect. This connectivity error is either due to a problem from the game server’s end, or from the player’s device or home network internet connection. 

When getting the connection failed error, COD Warzone 2.0 simply won’t allow you to play the popular Battle Royale mode at all.

Causes of COD Warzone 2.0 Connection Failed error

Connection failed error on Call Of Duty Warzone 2.0 is mostly caused by a server problem but at other times, it’s also coming from the player’s end. Below are the known common reasons for this error message:

Server is down.

Popular online games such as Call Of Duty Warzone 2.0 sometimes encounter major server downtimes that may last from a few minutes, hours, or even days. While Activision makes it a point to limit server outages, this type of problem cannot be totally eliminated due to a lot of things that could go wrong. So, the first thing that you can do if you encounter any connection error on COD Warzone 2.0 is to check whether or not it’s due to a server problem.

Unresponsive modem or router.

If the game servers are clear and there are no known issues at all, then the rest of the causes must be coming from your side. The first thing to consider in this case is the state of your network equipment such as modem or router.

Routers can become unresponsive if left running for a long time. Be sure that you reboot your own router at least once every few days to avoid encountering problems in your network.

Slow internet connection.

If you have slow internet connection at home, your PC, PS4, or Xbox One may fail to connect to the game servers in time. Slow connection can occur if you have an issue with your broadband line, ISP-related outages, or if there are too many devices using the internet at the same time.

Wifi signal interference.

Ideally, you don’t want to use wireless connection when playing competitive online games such as Call Of Duty Warzone 2.0. Wifi is less stable than a wired connection so if you are getting the connection failed error on wifi, you should consider using a LAN cable to connect your PC or console to the router.

Random game bug.

Sometimes, games simply crash due to a glitch or any new changes to the system brought about by updates. 

Damaged game files.

If you are positive that there are no known server problems and your internet connection is fine, your COD Warzone 2.0 connection failed error may be caused by a damaged cache or files. You should consider reinstalling the game if this is the case.
