Issue: How to fix Call of Duty: Warzone error "WHITELIST FAILURE" in Windows?
Hi, Call of Duty: Warzone keeps freezing and coming up with the “WHITELIST FAILURE” error. Any tips on how to fix it, please? I run Windows 10.
Call of Duty: Warzone is a first-person shooter game developed by Infinity Ward, Raven Software, and Activision. It was released on March 10, 2020, as the second installment in the battle royale subseries of Call of Duty video games. The second installment in the series, Call of Duty: Warzone 2, was subsequently released in November 2022.
With its intense gameplay, rewarding battle pass system, and free-to-play format, Warzone has gained immense popularity since its release. It is one of the most popular video games available today and shows no signs of slowing down, despite the mixed reception from gamers themselves.
Despite its popularity, Warzone has experienced some major errors and technical issues leading to frustration among players – the “WHITELIST FAILURE” error is just another issue that they have to deal with. The error can affect both Warzone games.
Call of Duty: Warzone error “WHITELIST FAILURE” is not too common code encountered by users – at least not as common as DEV ERROR 657 or “Your profile was signed out.” Nonetheless, a substantial number of people complained about it on the official Activision support page, as well as other forums such as Reddit.
In most cases, the “WHITELIST FAILURE” in COD occurs whenever users attempt to access an ongoing match, and the root cause of it is connectivity issues. While in some cases, the disconnects are related to the instability of Activision servers at the time, other instances relate to users' settings configuration or other issues on their PCs.
