This year, in spite of the overwhelming odds, blessed us with some strong AAA entries in gaming. The recent Cyberpunk 2077 comes to mind, along with hits like The Last of Us 2 and Spiderman Miles Morales. One of the most enduring, popular games of the year is, surprisingly, Call of Duty: Warzone. While most Call of Duty games launch to massive fanfare then quickly lose relevance until next year’s entry, Warzone breaks that mold.
Eschewing the template of the other games in the franchise, it successfully capitalizes on the popular Battle Royale format instead. And, as we always say, it does it very well.
With huge, expansive maps, dozens of players in each match, and routine additions of content, the game is huge. Even after over 9 months of its launch, the player base is only growing. With the addition of raytracing implementation, PC players (and Xbox Series X/PS5 owners) can even cutting-edge graphical innovations. And, as we discussed here, the new Season 1 update adds full integration with Call of Duty: Black Ops Cold War, along with a stunning new map!
Players on PC, PS5, and Xbox Series X report facing Warzone Developer Error 5476 when trying to matchmake
Warzone is one of the few Call of Duty games that has no single-player offering, and functions as a spiritual successor to the pivot Black Ops 4 took. That means all gameplay, aside from some optional training tutorials against NPCs, is all online. However, recently the launch of the Season 1 update sees unexpected errors when trying to set up a multiplayer match. The most common issue is Warzone Developer Error 5476, which occurs rather persistently for many.

As the image above notes, the issue was recently formally acknowledged by Treyarch and Beenox. However, there must remain some confusion for many players, as the issue affects all platforms. Here, the official Twitter account has only acknowledged the Zed 398 Swift Clover error, not the one the player referred to.
The Warzone Zed 398 Swift Clover error, as it’s known, is primarily a PC based error. On PC, it results in frequent notifications that pop up when multiplayer requests are made. This means that while trying to set up trios, quads, or teams in Warzone, the Zed 398 Clover error may occasionally halt the process.
The general consensus as of yet, keeping in mind the Season 1 update only just rolled out, is that the Warzone Zed 398 Swift Clover and Dev Error 5476 are linked. While neither Treyarch nor Beenox would confirm this, all signs point to this convincing theory. Both errors persistently hinder multiplayer matchmaking, along with crossplay.
And both occur specifically when trios and quads modes search for players. Furthermore, the indirect way Treyarch’s page responded to the PS5 player, with a status update on the PC error, shows both will need resolving together. Others note that Warzone’s crossplay mode, which allows PC and PS5/Xbox players to game together, itself may become the source of said bugs.
For this reason, we have taken the liberty of helping you troubleshoot and fix these Warzone Zed 398 Swift Clover and Dev Error 5476 issues. Keep in mind that none of these will guarantee a fix, as the issue is still new and inexplicable.
However, users online have reported success after employing these fixes. Keep in mind the fact that Treyarch and Beenox responded and assured users that they are working on a fix is a good sign. No doubt an official patch or update in the future will help immensely. Hopefully, you’ll be able to resolve Warzone Dev Error 5476 and Error Zed 398, Swift Clover, soon!
1) The old fashioned way – restart your system (PC, PS4, Xbox Series X), and your router
Sometimes, technology encounters issues that only some golden, tried-and-tested methods can resolve. This includes the infamous restart option. While this option sounds useless and outdated, it can accomplish wonders. Often at times, faulty processes or memory caches can accumulate, and slow down your programs. They can also result in errors while running games, like the Warzone Dev Error 5476. So, simply restart your PC, letting all processes close. Running them again can ensure they work properly this time.
On the console side, you can do the same. However, make sure you actually reboot them, instead of just putting them into the default Standby mode. On your PS5 and Xbox Series X, hold down the power button for several seconds until you hear a sound and it shuts off. Alternatively, access the main UI from your controller, and look for shut down console options.
When it comes to the router, this is simple as well. Simply power off the router for 30 seconds, then power it back on. Wait a few minutes for it to reconnect then retry Warzone. If you use a wired connection, simply unplug and reconnect your Ethernet cable.
2) Update your PC graphics drivers
Depending on your GPU brand, you may need to routinely update graphics drivers from different sources. We’ll assume here for simplicity’s sake that all GPUs come from either Nvidia or AMD. Basically, graphics drivers are software packages that stabilize, fix, and facilitate games on your PC.
Because developers constantly improve their games, drivers should be checked regularly for updates. For Nvidia players, check the GeForce Experience app for the latest drivers.
If you have an AMD GPU, you can look here for the latest drivers.
3) Repair Game Files/Rebuild game database on PC, PS5
If you’re on PC, keep in mind the constant influx of software sometimes leads to damaged game files. If you frequently encounter the Dev Error 5476, or Error Zed 398 Swift Clover, on Warzone, you may have faulty game files. Not to worry, though, because this can be fixed.
On Steam, simply open your Library and look for Warzone. If it isn’t there, you can add it manually by going to Add Non-Steam Game, and attaching the Warzone executable (.exe) file. Then, click on Properties, and go to Verify Game Files. This will allow you to rebuild the files without needing a full reinstall.
On PS5, you can do the equivalent by rebuilding the game database. This step is crucial as it can detect and correct internal memory errors, and reorganize your SSD, without needing a full reinstall. Power down the console, holding the button till you hear a distinct audio cue. This boots it into Safe Mode. Navigate to the game settings, and click on Rebuild Databases. This should help resolve your Warzone Dev Error 5476 right away.
4) Reinstall Call of Duty: Warzone
If all else fails, this is your last resort. While the above fixes should improve your odds, if you keep encountering Dev Error 5476 and Error Zed 398 Swift Clover you may need to reinstall your game. Keep in mind that Warzone has a huge download size relative to other games, so this may take time depending on your internet connection. However, hopefully, this will eliminate any bugs or errors in the installation.
