I have a nasty error in logs while using Epic Online Service…
I have registered my application on https://dev.epicgames.com/portal/ to get everything for EOS plugin to work…

UE5_plugin
UE5_plugin1176×915 122 KB

In DefaultEngine.ini i have added things that are written on The EOS Online Subsytem (OSS) Plugin | Unreal Engine Documentation

[OnlineSubsystemEOS]
bEnabled=true

[OnlineSubsystem]
DefaultPlatformService=EOS

[/Script/Engine.GameEngine]
+NetDriverDefinitions=(DefName="GameNetDriver",DriverClassName="OnlineSubsystemEOS.NetDriverEOS",DriverClassNameFallback="OnlineSubsystemUtils.IpNetDriver")

[/Script/OnlineSubsystemEOS.NetDriverEOS]
bIsUsingP2PSockets=true

This is the error that I get…

LogOnline: Warning: OSS: TryLoadSubsystemAndSetDefault: OnlineFactories does not contain [EOS]
LogOnline: OSS: Creating online subsystem instance for: NULL
LogOnline: OSS: TryLoadSubsystemAndSetDefault: Loaded subsystem for module [NULL]
LogOnline: Warning: OSS: EOSPlus failed to find the native OSS!

Just generate an encryption key online. Use this one for example, select 256-bit, enable the “Hex?” option.
