Call of Duty - How to fix dev error 1202

Dev error 1202 in Call of Duty: Modern Warfare and Warzone appears when trying to join online play during free multiplayer trials. Specifically, this code appears for players who have purchased the full version of Modern Warfare when they try to connect with free multiplayer lobbies.

This is a very specific error, but one that rears its ugly head during promotional events. Most limited-time events that include free multiplayer trials are designed to give newbies a way to learn the ropes. Players who already own the game stand to dominate the match, so they’re not really supposed to join in. As such, paid players cannot host lobbies with free players without encountering dev error 1202.

Yes, it’s a little bit confusing. Fortunately, there is a very simple workaround to fix error 1202: Make sure the lobby is being hosted by a player who doesn’t own the full version of the game.

Since lobbies created during free multiplayer trials are open to all, paid players will be able to join. Of course, it will probably result in a lopsided match. After all, new players will be like lambs to the slaughter when it comes to fighting against more experienced veterans.

If you’re encountering dev error 1202 during a free multiplayer weekend, try joining a different lobby. Pros aren’t supposed to mix with newbies, but you can get around the issue by making sure a free player is hosting.
