Dev error 6071 code is one of the most common errors that you'll encounter in Call of Duty: Warzone. It can be pretty frustrating but luckily, there are some potential fixes while we wait for the official patch.

Call of Duty: Warzone players have started to report various issues that are preventing them from enjoying Activision's free to play battle royale experience. Of course, this is expected since the game is out for less than 24 hours at the time of writing but many feel that the developer could have done a better job, stability-wise.

One of the most common issues at the moment is dev error 6071 code which appears after launching Warzone. Infinity Ward and Activision are yet to acknowledge the issue and while we wait for the official fix, we have a list of potential fixes that help you overcome the issue.
