Unknown Error FFFF in Red Dead Redemption 2 is a very common problem. For most users, it occurs when they join RDR online, but it can sometimes happen in single-player Story mode too. For RDR Online, it usually happens when they join an online session or launch RDR Online. This RDR2 error code is very vague and doesn’t help to narrow down the reason why it happens. Users who have contacted Rockstar support report that they haven’t been provided with any fix for this issue.

There are different reasons for this error depending upon whether you face it in story mode or in RDR Online. In multiplayer mode, the main reason for this error is the modders in your session. Rockstar Games has a history of letting hackers and modders run rampant in their online games and RDR Online is no different.
