Hello there @Knmak3d!
Checking around the community, this issue has popped up in other sccenarios. The main error to consider is LogEOSSDK: Error: Invalid parameter EOS_Auth_Credentials.ExternalType reason: invalid type, which aims at a routing issue with your credentials.
From what I could gather, the following changes are recommended:
- Set EASAuthEnabled=false in EOSGS:
[OnlineServicesEOSGS.Login]
EASAuthEnabled=false[OnlineServices]
DefaultSubsystem=EOSGS
- Switch ExternalAuth to ConnectToken
Params.CredentialsType = UE::Online::LoginCredentialsType::ConnectToken;
Params.PlatformUserId = PlatformUserId;
Params.CredentialsToken.Emplace(UE::Online::FConnectToken{ CognitoToken });
