Turning Crossplay ON

If you are playing Fortnite on console devices like Xbox, Playstation, or Nintendo Switch, then you might be experiencing party issues due to trying to connect with players from other platforms. Cross Platform play allows players across devices to connect. Here’s how you can turn Crossplay ON in Fortnite.

Configure NAT Type 3

NAT stands for Network Address Translation. It is a set of processes that translate your Private Internet Protocol or IP to a single Public Internet Protocol or IP. NAT type 3, or NAT is strict, is the most strict type of NAT setting that blocks all data traffic transfer from your Local Network. This is also the safest setting as it protects from almost every potential attack against your PC.

It sure has security benefits, but it also has some disadvantages. It prevents devices connected to your network from communicating and blocks your access to join other servers online. So this can be one of the root causes behind errors like Fortnite Error Code 91. This can also lead to constant lag, connectivity, and server accessibility issues.
